For anyone having this issue with there Saturn. I had 12v at the purple wire where it plugs into the blower motor. The ground wire was fine also. The blower motor still wouldn't work on any setting. I pulled the blower motor out, ran 12v to it, and it spun. So the motor was fine. Traced everything back from there in this video and everything checked out fine. I took the driver side kick panel off, and you can see the bulk connectors that connect to the fuse box. The far left connector is where the purple wire goes that powers the blower motor. I loosened the screw in the middle of the bulk connector and pulled it out. Sure enough where that purple wire connected into the fuse box was corroded and slightly black. Cleaned up the pin. Cleaned the purple wire connector the best I could in the bulk connector and put it back together and the blower motor works. If you have no low speeds, but have the high speed, it is most likely your resistor pack. If you have low speeds, but no high speed. It's most likely the relay. If you have no speeds at all, then it's most likely going to be a wiring/fuse/connection issue. Hope this helps someone.

Your Have Been Very Helpful In Helping Me Not Freeze When In My Car This Winter And For That I Thank You Good Sir!

[@MrMacsagitarius]

Thank you sir, this is the most easily explained step by step and helpful video about Heater Blower Motor Troubleshooting. At this moment I'm just about to hop from my computer to my car, which has a trouble working in the different speeds other than the high speed.

[@edmundochaparro-barriguete1215]

thank you very much. Your video helped me realized that testing the connections at the relay is very helpful. Because you could find if the switch is bad, if you resistor is bad, if your fuses are bad or if your relay is bad.

[@MiBzAn]

You just saved me, a frozen Canadian, over $100 that I don't have - thank you so much!

[@bhavi45]

Hi Richmond. Your videos are amazing. Iam an entry level technician would love to watch all your videos. Great work highly appreciated.

[@cobrastrike6043]

2:15 Before running out to spend money for a new motor, first check to make sure that it's not just a corrosion buildup on the terminal, in which case just clean it off, maybe apply some dielectric grease, and viola you just saved yourself some bucks to use for beer and pizza after a job well done.

[@BenHerbivore]

SATURN VUE OWNERS: There is an orange wire in a harness/connector behind the drivers side left kick panel that loses connection. May need to clean or splice/bypass the connector with that orange wire. SATURNALIA FORUM

[@joshuabirtch8689]

Sorry, you are correct. You are measuring current. DC; Direct current! The voltmeter works by measuring the current through a fixed resistor, which, according to ohms law is proportional to the voltage across the resistor. An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire...which is what you were checking for.

[@INNOsinz]

OMG i love you. The the day after i bought my Saturn the engine light came on :( and from that day forth its been falling apart! The vids on this series gives wonderful insight!

[@lacroix1976]

my 2000 sl2 saturn at 322000 km is still running strong , almost never break and when so , it s the best car i had for DIY repairs , and with the help we get on youtube.....for me a saturn is a little tank ^^

[@GTVAlfaMan]

Thank you Rich, I will check out your damper motor video and let you know what I find when I start working on the car.

[@joefazzari707]

This is extremely well done. Thank you for posting this video. It is extremely helpful and complete. Are you a shop teacher? If not you should be.

[@dugtucker]

great video ... had my dash all torn apart to replace resistor .. took my trusty ole simpson 260 V.O.M. out to double check ... found bad wire @ the motor plug in ... looks like the plug might have been HOT as it is slightly melted & disfigured. Found the same wire harness @ junkyard for $2.00 and spliced it in about 4" back from old plug .. works like a charm ... Plenty of A/C & heat NOW !! Thanks !

[@gasgiant7122]

Is it just me or does he sound like Peter Griffin?

[@banclaster8086]

Very helpful video. Simple and complete. Thank you.

[@RichpinTv]

Glad it was helpful!

[@tombonnema8627]

I would like Rich to explain how one can see current using a voltmeter, Every time Rich said you should see current there he was in fact looking at the voltage at that point. Presence of a voltage does not mean there is a current there. A voltage can exist without a current being present but current cannot exist with out a voltage. Current is measured with an ammeter and is placed in series with the load. Rich's procedure seems to be good but his terminology is sometimes wrong.

[@RichpinTv]

What year are you working on.

[@morganmendieta3738]

Thank you that was very well explained.

[@dlphoto]

Here's a question. I have a 2007 Dodge Durango. I made it to the early stage of this video where you check for ground. I didn't find continuity so figured there's no ground. Any idea, where the ground should come from? I put a jumper into that side of the plug and took it to ground and the fan works. I wasn't sure if I could just permanently wire something in like this or if there is an easy place to look to see why I've lost the ground.

[@RichpinTv]

I would start by testing the blower switch.We can rule out the radiator fan motor if it comes on when you turn on your A/C.I do not foresee a grand marquis video in the near future.

[@snyperbob]

Thank you for this video! Helped me out

[@jobamasux]

Thank you for making this video! I was able to diagnose and fix the problem with my heater blower motor! Mine turned out to be a bad connector at the motor! Unfortunately the wire that connects to the blower motor can be bumped by the passengers feet and cause a short! I corrected this by taking some electrical wire and pulling the wire up and wrapping the tape around the motor. wire and connector. This should prevent someones foot from inadvertently striking the wire!

[@jobamasux]

Sorry, I meant to say wrap electrical tape around the wire, motor and connector!

[@charlottehaynes8879]

jobamasux straight wire heater blower nothin.check hot wire on fire wall outside,& hot wire before relay

[@RichpinTv]

@69RSZ While the car is running what is the reading at the battery with the blower on.

[@AzureHoBo]

Hey thanks for making this video, the other day my dash started to shake when I turned the blower on. Looked at the fan and it was clogged with insulation material. Did you notice any of that insulation above the blower when you took yours out in your other video?

[@Rachel_Gordon]

This video is fairly old so I 100% understand if you don't reply but I have a 1994 Saturn sc2 n I have no power at all to the ign3 and hvac fuse in interior fuse box...checked all the obvious things other fuses/relays/fuse box itself the wiring in the blocks and the pins in those fuses spots and there is NOTHING out of the ordinary but I still can't figure out why there's not currently flowing to just those 2 fuses all the rest are good..so basically I have 2 questions.. 1: what do u recommend next? 2: do u know what feeds the hvac fuse? I looked in owners manual and some diagrams but can't pi point what actually send juice to the hvac fuse...any help would be GREATLY appreciated..thanks

[@Oicu8]

2001 sl2, blower works great... for the first 15 mins. The blower starts to slow down. Example: drove 15mins, on highest setting, stopped for red light and noticed my fan was blowing really slow. Turn it off, wait a few mins, turn back on and back to normal... everything checks out as far as testing goes. Any ideas? Thanks!

[@RichpinTv]

The only difference on this year is that the high setting goes trough the body control module on it way to the blower motor.There are only two fuse boxes on the s-series.

[@finddeniro]

Yes - The Fix Is In ! 4 Stars Thanks and Blessings....

[@rickivens798]

Hi..,. thanks for the video... I'm stuck at step 1... no continuity... what do I check? I "rigged" a ground wire from the blower ground pin connection on the blower itself to a door frame bolt and connected the power part of the connector to the blower motor and it ran when key was turned on, but only on high speed and it didn't matter what the fan control was turned to ... even when turned off, the fan still ran, high speed, as long as the key is on. Thanks for your help. My car is a 2004 Chrysler Sebring...

[@jdunny33]

I have a 2002 Impala and the blower just went out when I shifted from park to reverse. I checked began to check the DCV at the blower motor itself like you have here but when I was at the blower motor to check for voltage I do not get a constant voltage. It seems to have a slow drop as I continue to check it but is by no means constant or anywhere near 12 V. Would I continue to check the relays/fuses or would this possibly be something different. Thank you very much in advance.

[@RichpinTv]

I have seen the blower motor electrical connector contacts be the trouble in the past.

[@starcruise12345]

Nice video. Got a question. I have a 1996 Opel Vectra. The ac blower only worked if i turned the switch to highest speed ( 4 ). What could be the cause ? appreciate your help.

[@mhebay]

My 2002 SL blower would stop working for minutes at a time (no matter the speed). Now, it won't work at all. New inside fuse and new relay. Good current (12.4v) and ground (cont) at the blower plug. Blower motor worked when connected to a 12v jump-start. Could the resistor be preventing enough power from reaching the blower while still maintaining 12.4 v?

[@foxdmulder]

thanks for your great videos.

[@christianramos640]

How much does this process differ when attempting these tests in a 2003 Saturn Ion?

[@chrisbarry500]

My mechanic and I have done everything you've demonstrated here [btw. great service, Rich] yet I still can't get the heat/ac fan to work in my 2000 SL1. I've been told there is actually a THIRD fuse box in this car but I certainly can't find it. Do you have any idea what might be going on? It's getting cold out there. The fan, for a very brief period, was working intermittently before stopping completely. Help!!!

[@steverose8732]

really just need to replace current with the word voltage,not that big of a deal. thanks for your help. I'm not getting a good ground and the voltage shows up regardless whether heater is on or off. there is no air flow. what does this mean? bad ground or bad resistor?

[@AmericaAndAllies]

I am trying to debug a blower than will not run on the high fan setting. It does spin but slowly. Checked the voltage at the blower when on high and there is a voltage. Would that suggest that the blower resistor is bad? I will run the tests on the relay as you suggested. I think everything is going to appear Ok.

[@RichpinTv]

The lower fan speeds go through the blower motor resister before they go to the motor.So i would start by looking at the blower motor resister.

[@RichpinTv]

If the blower motor is not working i would start by checking for voltage at the electrical connector at the blower motor.

[@skylarhenry9310]

I guess it's kinda randomly asking but does anybody know of a good site to stream newly released series online ?

[@farmerinchico]

Very informative, thanks!

[@larrywebb8309]

excellent video , I have heat now

[@bertforbes1212]

I have a 2003 camry where the blower motors don't turn on. But when I check the wires at the motor, I have continuity to ground on both wires. No current on the hot wire. I swapped the blower motor relay with horn relay. This changed nothing. I am really not sure of the labelling on fuses and relays.

[@RichpinTv]

If the A/C has a full charge then there is a good chance that the motor is faulty.

[@dustdevilmedia]

I have a 97 SL2 with no Blower motor relay also. I'm diagnosing right now but so far blower motor connection show signs of burn and the mult seems to show the two wires are shorted somewhere.

[@RichpinTv]

@MrWill1985 Sounds like you have a bad blower motor i have seen them do what yours is doing.

[@Vaccutravel]

My man calling voltage current, even after he sets the meter to voltage. Current doesnt exsist without a load(resitance)

[@megaleadjp]

Thanks I just replaced my motor after checking fuses and found power to my motor. Resistor was good but got no air on all 4 settings.

[@ThePaulgregg]

Richpin ROCKS!!!

[@robgrode]

I still cant figure it out. I have voltage at the blower motor, but it seems low, like 10 volts, the switch seams to work(turning it up and down makes the voltage at the fan go up and down, but never above 10 or so volts. The fan motor is new, the relay is new, the switch is used but new to me, and i'm down to the last thing the resister. My question is: If I have LOW voltage at the blower motor, does that mean the resister bad? Also, is there any way to test the resister before i go buy one?

[@philash8622]

Hi, I have an issue with my heater/ defroster/ AC. When I turn it on nothing happens. It doesn't work on low medium or high. I have rear defrost but that is separate from the other controls and uses those lines on the window when I press a button. Any guesses? I would hate to buy a blower motor when it could be something else.

[@MrWill1985]

@richpin06a What was your blower motor doing? My 2009 Ford Focus blower motor works properly when I first turn the blower on but after 20-30 seconds later it stops working. My father checked it the same way you did and informed me the blower motor went up. So I got one on order right now. Do you think it is the motor? One source says it may be the switch. So I hope I didnt spend $97 for nothing.

[@maxie0789]

Hey. I'm getting a high voltage when I test the switch power. What could that mean?

[@RichpinTv]

Thank you for 411.

[@Kelly123456]

i have a 2004 mercury grand marquis gs and my blower motor only works on low speed when u first turn it on could it possibly be a bad switch or could the blower motor resistor be bad and also my radiator fan is not working the car ran hot and the fan never kicked on at any time could the sensor be out in the radiator fan the fan is a 2010 if so is it better to replace the sensor and fan altogether and if so can u do a video of a replacement on how to do it thanks

[@HisDudeness2020]

Here's my issue. I drive an 06 Chevy Equinox and replaced the blower because it gave out on me. I got a new one, it worked for 2 weeks before it stopped, ended up getting a refund for that and got a replacement. Still nothing is working. I tested all the fuses and relays in relation to the Blower motor and they check out okay. I have noticed that I have no continuity at the ground wire (purple wire) and have power flowing through the red/white wire. Here's the kicker though, there is power going through the red/white wire whether the ignition is on, the AC is switched on or not. So what could be the possible issue in this regard?

[@TheLastman23]

Resistor?

[@michaeld1738]

Can this same concept be used to diagnose other makes/models, or is it specific to the Saturn S-series?

[@RichpinTv]

The colors of the wires will be different from vehicle to vehicle.

[@RichpinTv]

@dahoss65 Sounds like a possible bad connection somewhere.

[@DesertEagle90]

Thanks for the video Rich. I'll defiantly save this video for studies but I have a question. My girlfriend have a 2005 Dodge Neon. She puts her heater on and it squeals very loud immediately. But goes off right away when she turns the heater off. That would be a Blower Motor issue as well right? Bad bearing on it perhaps?

[@RichpinTv]

That does sounds like a possible bearing noise coming from the blower motor.

[@eaymonddull]

DesertEagle90 I realize this is super old, but on my old neon it ended up being the alternator slipping on the belt when the blower loaded it down. New belt made it go away

[@RichpinTv]

You are right i need to get my terminology in order and i will make a determine effort to do so in the future.

[@SCHNEIDER2862]

You did a good job!

[@IamKurr]

Excellent job showing the diagnostic route of the circuit

[@ein99999]

the resistor goes on the blower motor causing it to blow slowly and thats the first thing that goes on toyota tacomas at least mine did and replacing it will give you a brand new like high speed full speed blower motor once again after you replace it . Usually the blower motor goes and it doesnt even turn on but if its blowing slowly then its likely that you need a new resitior for the blower motor and many times its right underneath or right next to the blower motor.

[@ram0166]

How do you get the electrical connector off. I pulled on the rubber part just like you did in the video and the thing won't budge. I tried using a screwdriver to pry it and all I did was bust off all the hard plastic parts.

[@RichpinTv]

If you pulled back on the connector before you pulled down and you can not remove the connector then there is a chance the connector has overheated and melted in the plug.

[@Turismo860]

somehow i dont have the blower motor relay cube. im guessing a passenger kicked it off at some point (the cover is missing anyway) how much do the relays go for?

[@RichpinTv]

+The Saturn Life A new aftermarket one goes for about $12.

[@josephknight4023]

I'm trying to fix the blower on a 01 Saturn SL1. The blower works when hooked up to a 12v source. I have good ground and voltage at the blower connector, but only when there is no load. As soon as I plug the blower in or add test light I get no voltage at the purple wire. Any ideas? I tried swapping the relay with the fuel pump relay with no success. When metering the relay socket, I have good ground and voltage on all three bottom pins (when the blower switch is on).

[@RichpinTv]

On this car control for the blower goes through the BCM.I have not as yet troubleshooted this set up.

[@Altobellodobermans]

My meter has two settings on my meter which are DCV and DCA which one do I use? Also on the ground wire test I have nothing coming up on meter. So does that mean it is my blower motor thats toast?

[@Altobellodobermans]

I used both settings and not getting anything.

[@donaldking6699]

Thanks for the great diy on how to check all this - IF there's current. I have none, not even to the ING 3 fuse. Since your troubleshoot was on a vehicle that was in proper working condition, power everywhere, great ground, etc. However, there's nothing - no advice as to where to go next if there's no power even getting to the first fuse. Without power I'm dead in the water. The fuses are great, look almost new, and the blower motor and relay are probably good as well - except, how do I find the disconnect, where to start. I'm really kind of under a time constraint. My 79 year old mom lives in MO, I'm in Reno, Nevada and she's having problems with somebody who wants to steal her property. I need to go see her asap. This is a project car, was before her troubles started, now, I'm putting it together as swiftly and correctly as possible. But it's an auction buy and has all kinds of title issues like no heat, no defroster, etc. Can someone please help me out here? I I'll be most greatful.

[@RichpinTv]

A bad motor can blow fuses melt electrical connections and make abnormal noises.

[@kickahaw]

thank you !!!

[@INDUSTRIALIST1234]

Great video. Please let me know the following. 1) What are the symptoms of a faulty blower motor ? 2) Is it possible for it to affect both the a/c and heating at the same time. Please let me know.

[@thomashughes9246]

Yes it is the same motor for A/C and heat.

[@robbrown8026]

Hey Rich, when you are checking the ground of the blower motor electrical connection, what ground in the cabin area are you touching the black multimeter wire to?

[@richpin3041]

I was using the negative post of the the battery for ground.

[@robbrown8026]

Thanks for getting back with me. Your videos are an amazing resource, so thanks for taking the time to put them up!

Do you have to go clear back to the battery or can you find a metal strap or something connected to the frame?

[@RonaldDarbyshire]

[@RichpinTv]

+Ronald Darbyshire Is the alternator charging the battery.

[@ragoo43]

Hi richpin . My blower motor won't work on high but all other speeds it does. When I check the voltage at the blower plug there is 12 volts. I do have continuity to ground. Could it be a bad blower motor? Thanks

[@RichpinTv]

If the plug has ground and the purple wire has good voltage with the switch on high the motor should work.Doing a bench test would confirm if the motor is good or bad.

[@lostoffroad3914]

ragoo43 that would be you blower motor resister if the motor works on all other speeds then the motor is good

[@1monsteraddict]

What if im not getting more than 0.43v though the connector, relay, or resistor?

[@richardcollinson8792]

My wires are sure of a hell harder to come off than his were

[@MrVegasTube]

Hi Rich at 2.06 you mention "if you see current there then thats the problem, the motor is bad..." (checking the purple wire) Thats where im stuck because I got continuity at the black wire, but at the purple wire (meter setting at 12 vdc) I got no current there (0.00). So I went ahead with each step thereafter and I checked off "ok" on each step you provide from there. to the end. The blower dosent work. Continuity at the black wire, check. Current at the purple wire, no. Ground at relay, check. Live current at the socket, check. IGN fuse test light, check. Connection to the switch, check. 15 amp fuse, check. Check resistor, check. So could it be the switch? If it is. could you do a video to show the replacement procedure my friend. I would appreciate your kind guidance with this. Thank you in advance and God bless you and your family for all you have done for so many years for all us little guys.

[@jerrymorrow5209]

a multimeter can measure voltage and resistance, and also 'current' across a load (I = V/R) !!

[@edmundochaparro-barriguete1215]

[@GTVAlfaMan]

Can anyone help with a 96 Saturn SL2 problem? Started my car today and turned on the heater fan and the fan blows fine but I hear a clicking sound from under the glove box area. I found that if I push in the "re-circ" button with the fan switch on the clicking sound under the glove box will stop. If i turn the fan switch on for ventilation, heat or for normal AC the clicking under the dash comes back. Now I must drive with the re-circulation button pushed in to get max AC with no clicking. Why?

[@adill2019]

Why are you going backwards you had power as far as the motor?

[@IamKurr]

Probably to show full diagnostics of the circuit

[@bradenbenoit5381]

I installed a new blower motor and resistor and fuse is good and not getting any power to it still what would the problem be??

[@BenHerbivore]

Relay. Or bad connection somewhere. My 2006 Saturn Vue had a bad connection at a specific power wire. Common problem. I could have spent hundreds on parts but it ended up being a free and easy fix. I feel bad for people who take their car to a shop. The internet is the place to go if you have even a bit of skill. Technicians will waste so much time scratching their heads, throwing parts, and charging you $$ the whole journey.

[@TheDheinze]

My blower stopped working in all but the highest setting for about a day, now doesn't work at all (2008 chevy malibu LT 2.4l) i'm looking to replace the blower motor resistor but thought I would check the blower motor while I was down there. Does that fact that i'm reading around 15v as opposed to 12v from my purple wire matter? could I have burned up the blower motor?

[@RichpinTv]

+Daniel Heinze Is the voltage at the battery this high.

[@TheDheinze]

+richpin06a yeah I guess I do, so does that mean since I have the volts coming in but no blower activity that my blower motor is no good

[@RichpinTv]

+Daniel Heinze That high of a voltage at the battery might mean there is a possible problem with the alternator.As far as the blower if there is ground and voltage at the connector at the blower and it does not work then there is a very good chance the blower is faulty.

[@mattcasdorph]

May be the blower motor resistor, it has 2 coils that control low, medium, and a bypass which goes straight through for high setting. If high works it has to either be the switch itself wearing out or the resistor.

[@RichpinTv]

No i did not see any insulation.

[@kraziek316]

Ray Romano eh!😂

[@RichpinTv]

It could be the motor is drawing to much.

[@aikalo80]

richpin06a hello I have 2000 Saturn LS1, and when I turn my AC on, it comes out through my dash vents towards the windshield and not through the front facing vents. I have had someone check and couldn't find and hose or valve leaks. Any idea why?

[@DollaBill101]

I am currently trouble shooting my sw1 blower motor as It stopped working on me. I tested the connections at the motor and the ground was good, but I was not receiving power to the motor. My fuse box is a little different than yours, and it appears I don't have a blower motor relay... htt p://i.imgur.com/2VwHfv7.jpeg I noticed the recirc fuse was blown and I replaced that, but I am still not receiving voltage. Where else can I check? Thanks!

[@afzalrana2120]

Hello mr give me answer why blower motor is not blowing car a.c

[@whynot9068]

2:10 can someone explain what he means here? Seems like he misspoke about 2 things: 1) "current" vs "voltage" and 2) he said " if you see current" and "if you do see current" but gave 2 different solutions (or next steps). Seems like one should be that you do NOT see ["current"] voltage

[@finddeniro]

Good job; right Around The Bases... (baseball )...

[@reynaldoreyna839]

I have a 2005 Chevy malibu the blower motor turns on randomly...even with the key out of the ignition

[@MrScotty46]

my blower switch works 'sometimes'

[@billyferguson8846]

This my problem on my 2000 eldorado. The voltage just stops going to my. Blower. Then if i turn the car off most of the time voltage will return. Anybody have any ideas?

[@jamesblackburnlynch]

My 2001 SL2 blower motor works on low speed (1) and high speed (4) but not on 2 or 3. I checked the resistor slot as you said in the video and found 12 volts there no matter what setting. I kinda thought the voltage would change as it went through different resistance circuits. If the resistor pack is fine, why are 2 and 3 not working? Weirdly, sometimes when the blower motor is going at speed 1 (which it does as I move it from 1 to 2 and 2 to 3), sometimes it jumps to 4. Any further advice?

[@RichpinTv]

Have you checked the blower motor resister.

[@jamesblackburnlynch]

richpin06a Well, I removed it and took a look. Nothing obviously burned out. I checked ohms across each set, but wasn't really sure what to look for. Any idea what the range should be? I had set the multimeter at 20K but I've seen that they might be more like in the 1 ohm range. Should I see a raising of resistance for the lower speeds? Why don't I see a lower voltage for each speed at the relay?

[@RichpinTv]

James Blackburn-Lynch Are you seeing voltage at the purple wire in all speeds.

[@jamesblackburnlynch]

richpin06a I just don't understand this. I have 12.3 volts at the purple wire in all four speeds. 0.4 volts when off. I thought the whole idea was the resistor pack lowered the voltage sent to the motor. But it's the same for all speeds and somehow, speed 1 is very slow and speed 4 is very fast (and speed 2 and speed 3 are usually going speed 1 but sometimes pop up to speed 4). Any clues?

[@RichpinTv]

James Blackburn-Lynch Have you seen this video i did kzbin.info/www/bejne/pnyWlaCcd8-Ff5o

[@thomashughes9246]

It's Voltage not "current," but aside from that, good video. Except you didn't check the coil resistance of the Blower motor itself. If you suspect the blower motor is bad, why not start there? If the blower turns at all on all the speeds the problem is NONE of the things you checked. If the problem is only one fan "speed" only then is it the resistor (not worth the effort to replace for loss of one speed). My 1996 SL1 has 257,000+ miles on it and the original blower motor is just starting to go bad. Speeds vary widely with no change in controls. I was surprised to find OEM replacements for $30 - 100 all over the place.

[@raykeefer5136]

My 97 sl1 saturn the blower works but not on high, what could it be.

[@richpin3041]

There is no relay so i would be checking the switch.

[@maxie0789]

When I test the voltage on the switch it jumps up to 18+. What could that mean?

[@RichpinTv]

What is your battery voltage.

Jeffery Hall thanks man. Forgot to say, I fixed it. I thought it was the blendoor to, but I checked easier stuff first. It ended up being a vacuum hose

Good job.

Jeffery Hall thanks man

I have current at the motor connector, I changed the motor and it still wont turn on. If I have current at the connector why in the world will the fan not run when it's a brand new AC delco

[@aciddiver1978]

Because you probably have a faulty resistor

[@RichpinTv]

You have a possible bad damper motor.Check out my video "Recirculation Damper Motor Removal"

[@Kelly123456]

the radiator fan doesn't come on when the ac is turned on like it is supposed to do

[@1bygoneby2]

On your video you keep saying check your current when actually you were measuring voltage with your multimeter set to the DC range at all those test points!

You don't address what needs to be repaired/replaced if there is NOT continuity in your very first test of ohms on the Black wire going to the plug to the blower motor. My black wire is slightly melted at the connector and there is high resistance (no continuity).
