Ford Econoline Vans: Blower Motor Switch Failures Causing Meltdowns!

[@brobrio]

I have a 93 and have this exact issue, except my 1 and 2 speeds always worked. I noticed a smell and saw smoke and knew there was a short. Thank you for showing us this!!!

[@JaMarvelousjmar]

I've learned so much from this guy. It doesn't seem as complicated once he guides you thru the process. Thank you so much and keep up the good work

[@Brian-bg2cb]

Totally made sense and straight to the point. 2000 E250 106,000 miles. You described the exact sequence of events that I experienced in the gradual diminishing of my blower. Racing to beat winter here. Just changed out my totally clogged heater core, so now I gotta get this blower working again. Thanks a bunch!!

[@markk3652]

This happened to my 2003 Durango. The blower motor resistor failed, so upon disassembly, found the plug in and harness mostly melted. I got replacement parts at the parts store, and wouldn't you know it, the new harness had beefier wire, but every one of them was the same color green. Good thing I have the electrical smarts I do.

[@22howards]

GM Astro does this also difference is, the fan switch is part of the control head 👎. Every car has issues. At least we have videos like this to help us repair our rides 👍 Thank you!

[@fsu3784]

Got a 2001 e250 and this is exactly what is happening to me. Thank you 🙏

[@eliteman7685]

This has been a common long running issue…I deal in 72-76 Ford Torino and Mercury Montego cars, and other 72-79 Ford/Mercury intermediates and this has been an eternal issue. I’d love to have a better way to rewire the system running off relays for the high current side.

[@dannyl2598]

Thank you. Once again you have saved the day for me. My switch melted and then melted the knob, it was so hot that the metal shaft burned my finger one the knob came off.

[@rodneybrand8521]

That looked good compared to some of the ones I've had to fix..

[@RiteSideup-nh6kn]

Every E350 I have on the switch always goes out I finally had a van where the motor went on the fan

[@franciscoamaya2945]

Thank you for a great video I have been struggling with a 2011 econoline with the same issue and thanks to your video I was able to figure it out I'm so thankful to you

[@williamallen728]

Very helpful video. I was able to repair my van thanks to your thorough instructions.

[@servingme09]

Thanks for info.....now I won't be frustrated with replacement of mind...and why 3 parts are needed.

[@josephsfields]

I appreciate your videos. I'd not mind watching the highlights of the actual component remove and replace just in case there are little plastic bits in the mountings and connectors that are prone to cracking or tricky disassembly. Keep'em coming. Ford does make me loco but so does my Chrysler, Buick and Mitsubishi. My only vehicle that doesn't is my 2012 Fuji Gran Fondo 2.0. 👍👍👍

[@AntonioClaudioMichael]

This has definitely been a common problem over the years since the 90s

[@twistedwrench490]

As usual great information great knowledge your awesome man!

[@Thecarguy1254]

Looks like the exact same switch panel at my grandmothers old 92 Aerostar, crazy how long they kept some of those parts.

[@jasont7887]

love your channel. i have a similiar van that the blower works on low and high only and not the two middle speeds. i've replaced the resistor and fan speed switch and still not fixed. this thing is driving me nutty

[@joshbigman1745]

I just fixed this issue on my 08 van. I hit a hump in the road in winter and my blower motor stopped. What I eventually found out is that the connectors to the blower motor and the speed switch were fried, and the blower resistor was corroded. So I replaced all those and then the AC fuse burned up too because the AC relay was soo corroded due to salt and water. So I changed all that and now it works great. Also if you are wondering where the AC relay is, it's in that weird box under the hood right infront of the driver's side. Those relays are not easy to find unless you order them or pull them from a junk yard. It's not the same as the blower motor relay in the main fuse box under the hood. I'm just sharing just incase someone else has the same problem.

[@johnviewer2305]

Do you all like my personal ford tec....lol...Brian has his act together fellers....the go to guy....thx Brian...

[@RadDadisRad]

Hahahaha, that’s happened to me a couple times. 390k miles on my junk

[@DavidBrooksNYC]

i watched this video and replaced everything but the harness !! yeah I'm an idiot!, if you do it exactly the way brian says man you will not have a problem, he is solid on the money

[@ericgustavson8293]

Good video, covers both possibilities. My fan was only working on the lower 3 fan settings, no high. I replaced the resistor, no change. Then I replaced the burned/ melted pigtail & switch, now works perfectly. It's a bitch to get to in a 2010 E150, doesn't have the same easy access panel of the van in the video. Thanks!

[@andrewjacobson556]

Very helpfull i have a 99 now i know what to look for thankyou!!

[@acemobile9806]

Correction, did not stop making them. Still alive and well in stripped chassis form. I deal with this all the time in U-Haul trucks. Standard practice is switch/pigtail/resistor on all of them I come in contact with. I also use Ox-Gard on all connections. The switch is a hopelessly cheap design but is easy to diagnose & change.

[@FordTechMakuloco]

Yup I know the heavy duties are still being made but I am talking from the passenger van side of things.

[@JeffLudwig-i5x]

That was a great video. My problem exactly.

[@boondockingmainahs]

I have the 2013 e350 and my fan only works on high too ! Do you have the part numbers for the pig tail , resistor , and the switch ? Thanks for the video

[@joecloud4622]

Thank you for you knowledgeable and concise advice!

[@quicklooksentertainment3217]

Aloha Brian, Thanks for a great video. My 2006 F250 had the same problem. Replaced the resistor and switch but noticed the female connector behind the switch is overheated. I could cut and spice a new female connector but so see you have a Motorctaft Kit there...is the kit the repair for the wires? If so, What part number? Thanks again.

[@ferminsalas9772]

I wish you would've came out with this video a month ago. This situation happened to my 2014 F150 Ecoboost. Blower burnt also.

[@ganormand]

Thank you for helping me fix mine. 2001 E150

[@medtec6747]

You also want to check the ground for the BM resistor it's by the accumulator drier often the bolt is very rusted and it can caused increased amperage through the switch

[@FordTechMakuloco]

Can you explain how a corroded ground can cause higher amperage pull on the switch? Are you saying the ground adds another load in series with the blower motor? Kinda like the resistors in the blower motor resistor? I would think the circuit would break before pulling more amperage, if it did the bolt and ground wire would be hot and melt in some cases.

[@medtec6747]

Didn't mean any disrespect bryan in my experience the increased resistance causes the motor to spin much slower sometimes stopping it letting it sit on one spot on the commutator of the motor passing more amps at a lower voltage than the motor does on high setting which leads to the wires and switch settings for the lower settings to get very hot, also it seems to shorten the life of the BM quite a bit. I may be misunderstanding whats going on but I've had several trucks in the fleet with this issue and that ground always seems to be corroded along with it.

[@edman1015]

Brings back memories for me

[@richardcassinari7026]

Great info...please start including part #s for all parts required to do the repairs...

[@FordTechMakuloco]

I always do including the special tools needed for a job unless there is an instance like this that there are so many variations it would be impossible to list parts for every year and trim level. I don't want to mis lead viewers if I don't have the correct info for their particular model.

[@lefthander5]

I have also had several that the blower motor(although working correctly) was drawing to much amperage..... change the blower motor if you are repeatedly changing switches.

[@FordTechMakuloco]

I have never come across that before in all my years. Was the motor shaft binding when turned by hand or did you compare the amperage draw from another known good econoline in the shop?

[@lefthander5]

@@FordTechMakuloco compared to other vans we had.

[@10813mike]

Yes that’s a good point. I’m just a home mechanic but just changed the resistor and harness on my 2001 F250 and a few years back on my old 4 runner and both fan motors were tight and seemed to be drawing more then they should so went ahead and changed them both also. Not too expensive for the piece of mind it gave me. Great videos! I really appreciate your detailed instruction!

[@FordTechMakuloco]

If this were an isolated incident I would have changed the blower motor also but for the econoline vehicles this is quite common of a failure no matter what year.

[@lefthander5]

@@FordTechMakuloco the most common fail for me has been the switch.... we have had a handful of them that would go through a switch every few months and found that the blower motor was the culprit.... and the funny thing is they were not squealing at all.

[@jimmieanderson8263]

i have a fleet of e450 vans the earlier ones i had the issues of melting the switch even with new motro and resistor i ended up running the high through a relay took care of the issues now to be fair i have e450 shuttle busses and have carrier ac units

[@adriendeboer5798]

Fixed a few hundred of them. Sterling heavy trucks same parts same burnt up parts

[@milcotto4153]

That is crazy. Why isn't Ford doing anything to fix this? It is their fault.

[@shawncrittenden6216]

Well thanks for the Vid but would have been nice to have the Part numbers for the Pigtail kit/Switch/resistor included plus the hardest part of the whole project how to remove the Bezel around/in-front of the switch panel.

[@1artisan]

Great video. My problem is the same but instead of blowing only on high speed. mine only blows on low speed. Any suggestions for me?

[@snoopdogie187]

I guess this is still better than the sprinter vans. I worked on one that the blower motor just rusted up and seized. It happened around 100k miles on it and only 4 or 5 years old. This was on a van used almost everyday, as you can tell from those miles. These three parts in this video cost less than that one blower motor also.

[@milcotto4153]

I have heard of people having had the blower motor changed on a motorhome on a Sprinter chassis, but they can't get it to work again.

[@eliteman7685]

I'm doing research on the econoline blower fan motor, for upgrading the 72-76 Ford torino blower fan, this is nothing new! Never understood why FoMoCo rammed all the current through a switch. Also seen the full size Chevy vans really suffer from the same issues of control unit burning up and failing. I used to manage a small fleet of Ford Econolines, and Chevy full sized vans.

[@tlferro]

Oh how I wished you would have filmed how you took out the panel

[@AntonioClaudioMichael]

As always Great Informative demonstration video @FordTechMakULoco

[@juancarlos1015]

Thank you so much!! Your videos are pretty informative.

[@BeRealAlways]

Do you have the part numbers for each of the items you mention in this video? Thanks

[@drjohnsmythe2968]

That was jacked!

[@johnsegard2948]

Keep up the good work. Thank you.

[@davidrte.664]

In the 1970’s Fords we had a similar problem with the AC switches, in high blower it would burn the switch up because all the current ran through the switch. We would put a relay so in high blower would be run through the relay. I don’t know how those are wired. But would that help with that setup.

[@MrPattyurso]

Don't even own one, but still love to learn. 👍

[@ffc3476]

Thanks for sharing Be well be safe

[@josevaldemar4587]

Thanks again great job

[@PhillyDee215]

Yup, common on these vans👍

[@markf1441]

Good job you look like always ! Respect .

[@Iloveorganicgardening]

I just wired my switch so tha Only the high works. But my fan still goes slow sometimes and fast others to others I'm thinking I need to bypass the resistors as well?

[@manolocordovez9323]

Thank you!

[@roberttucker68]

question is this the same for it stuck in low mode / i pull the knob of and the switch was super hot . or is it a short in the wiring?

[@joelb360]

Thank you for this video!

[@lazaromiranda56]

Hello, I have 2003 ford 7.3 diesel. The speedometer does not work. I replaced the both sensors. What else can I do? Thanks

[@pamelamatheny4613]

Could a melted pigtail cause the ac to blow off and on intermittently? The blower control switches for front and rear were replaced, but they didn't replace the pigtails. Im not sure if he even looked at them since he didn't pull it out like you did. And worked from underneath it. Replaced the blower motor and the resistor for the front and rear. The front and rear ac goes off and on intermittently.

[@jesussavessinners123]

Thanks.

[@philh9238]

Should you change the blower motor as well due to high ampere draw?? So the new harness and switch don’t get burnt up

[@FordTechMakuloco]

Never seen one cause this in my 20 years of wrenching. This is a common issue with the e series new or old.

[@tiburonrodriguez8902]

I have a question. I have a ford expedition xlt 2004 and the back a/a unit doesn't blow cold air. Also the front a/c goes on and of in all speeds, any ideas can help me out I will appreciate it. Thanks and also your channel help me a lot with my expedition.

[@hotmechanicak]

I have one that continues to come back with the switch melted. We replace the switch, connector and resistor every time. One we even replaced the blower motor as well. It continues to burn up switches. Can you help?

[@brandonc2233]

Is there bulbs in the heater controls?? Mine do not light up at night. Radio, cruise buttons, dash everything else does. Except the heater controls. Kinds erks me because I csnt see them st Nighy so it's a little annoying. I guess I need to pull the Hester control out and see. From photos I've looked at I don't see any bulbs for them. R the dimmer.lights built into the whole unit?

[@csnr355]

What about if no speed at all, do you think is still the resistor?

[@pasteasplaintext]

I have the same issue. No speed works but when I drive on the freeway, I can feel the faintest cool air coming out of the vents.

[@sammysokosammysoko]

​@@pasteasplaintextThis is happening to me right now. Did you ever figure yours out?

[@edgar12345632]

Hi do you think using dielectric grease helps to prevent melting connectors ? Thank you for your time to show it.

[@FordTechMakuloco]

No the melting is caused by worn contacts inside the switch assembly.

[@regbrown2110]

Man this is not related to this video but I have a 15 f550 roll back with a 6.8 that has an surge issue nobody around here can diagnose. The a/f ratio pid keeps flopping back and forth . I've replace fuel pump ,fuel pump control module, pcm ,maf sensor ,evap purge solenoid. The intake has been smoked twice no leaks . All parts replaced have been ford parts . Any ideals ? By the way when I first purchased it (82k and recently rebuilt by a ford dealer) would randomly do this once a month now it's an all day everyday concern.

[@tomtheplummer7322]

Bad switch. Thought that’s what the resistor was to protect. Dang.

[@mflip9150]

Mine only works on 4 like you said in the video, also it only blows on the floor none of the other settings like vents or windshield work. Would that be a switch?
