How to test and fix - no air flow. A/C not blowing, blower not working, no High or Low fan speed.

[@KatelynLuvzWeezy]

So many people tried to explain the blower motor resistors and you're the only one who made sense.

[@maelo9x]

Excellent explanation!!!

[@ThomasMcClaughry]

I'm and Electrical Engineer, and think this is an extremely well thought-out and accurate tutorial that should apply generally for any car blower motor system. Well done!

[@CorbinBerriman]

My Blower motor works just fine , speeds and control all works 110% but the second I start my engine it turns off completely and it stops working. Why would that be, he doenst talk about it in video so thought id try you since your some engineer bloke?

[@RomanReviews11]

@@CorbinBerrimanyou would have to check the fuses and go threw diagnosing your car.

[@FromMetayou]

​Does it blow a fuse doing this it could be an underrated fuse if so

I’m a 65 yr old Grandma who looks everything up on YT and I just want to thank the person who said smack the motor. You are the bomb!! After checking fuses, and relays and Freon, I found this comment and went downstairs and gave it a whack and boom it worked. I’m so happy😂😂😂😂

I had problems 1 & 2. Didn't know how to explain it to the mechanic & got charged almost $100 just for him to look. I found this video today. You did such a thorough job of explaining everything step by step & using drawings. Now I can go back & tell him what I think is going on and I wont have to keep using the term "thingy" to describe the problem. You'll definitely be getting 5 stars from this grateful mom!

I have no power to my resistor at all, The first two explanations were very in depth, and I was hoping you would do the same for my problem as well, but you only told me what I already knew, that I needed to test power or resistance to the switch, and I’m not sure how. Still a great video. More descriptive than anything I’ve seen so far.

Muchas gracias por su video, fue de gran ayuda, he resuelto mi problema de manera fácil y práctica, gracias por compartir sus conocimientos maestro.

[@ashbowmusa7512]

thanks for the great tips, my question is how do we look for the ground as mentioned at 9:20 or around that point? my case (sienna 08) is that there is no power at the control key and no power at the resistor, the fan is running good when connected directly to the battery terminals. this point is very important and left unexplained.

[@MakeItEasyMechanic]

To look for ground you set your multimeter to DC voltage and connect one lead to battery positive terminal and use the other lead to touch a potential ground. If your multimeter shows voltage - you found your ground. But I would think it should be a power control switch. Therefore I would look why there's no power coming to the switch first, maybe it's just a blown fuse.

[@CJL2022]

Ever find out what fixed your issue?

[@jameschild1321]

Perfect explanation!!!

[@NirmalSingh-gf8ef]

Aye bro you nailed it Simply nailed ❤

[@macknumber9]

This video is gold. I was so confused on how it works and now I have such a good understanding. Now I can diagnose using common sense and some actual testing of voltage at certain connections. If you find the problem is the blower motor is it really important to change out the resistor too? And vice versa if you find the resistor is the issue do you have to change out the blower motor too?

[@MakeItEasyMechanic]

No, I would just replace what's bad

I took mine out and it tested fine with my multimeter, put it back in and it worked lol I don't known but I'll take it!

[@jxg151]

Thanks a lot...I finally found a video that makes sense. My situation is scenario 1. It has not completely paced it - it works intermittently - when it does work (sometimes after several minutes of driving), it works at all speed settings. However, some others say that you should not change the blower motor on its own; that the resistor is almost always also compromised, so it should be changed as well. What do you think? Based on your logic, the resistor only needs to replaced under scenario 2, which does not apply to me, since my only issue is scenario 1

[@louisbeeston7647]

This is exactly what I need. I have a Renault twingo and this helped me get my head around what’s wrong. Shame I have to take the dash off to goer to what I want lol

[@carolsisti7203]

Thank you so much for the video. I have changed the blower motor resistor but after couple of days it has failed again. What's the story in this case?

[@UniverseStrongestWarrior]

THANK YOU. turns out just smacking my blower motor made it work 😂

[@keithlutnes]

Great video. With my blower motor only on occasion it doesn't run whether heating or cooling. Then all of a sudden it starts working. I've changed resistor and blower motor. I suspect a loose connection but I don't think so. After your video I'm thinking a relay.

[@fireadept007]

You worked in reverse order.

[@JThom-yh3ef]

I changed the BM, the BM resistor, and the relay and was still giving me problems until one day it came to my mind that it can possibly be the climate control module. So I dismantled the center panel console on my ride and switched out the climate control module, and it all of a sudden worked like magic. Long story short, it was my climate control module that was defective.

[@nadialaraqui9674]

Thanks, I’ll try to do it tomorrow

[@jessicathomas8640]

great tutorial legend

[@TheKfinnas]

What setting did you use to test the blower motor

[@wflyer7985]

Thank you for the video. I replaced the resistor, the motor and still nothing. I checked the voltage at the blower fan plug and I’m only getting 7-8 volts across all the four blower settings. Why would I not be getting 12 volts? Thank you for your help

[@brulextrulex]

Excellent!

[@jcweights]

Thank you for this video, it's very informative and easy to understand. I'm wondering if you have a video covering the digital/automatic climate control type A/C systems that you mentioned at the end of the video? My wife has a 2015 RAV4 XLE and her climate control will sometimes reach maximum speed. Sometimes, it's immediate. Other times, it won't reach maximum speed until we pull into the driveway. Would her system still have a relay? Should I replace that first? Would the "Blower Motor Transistor Module" be the second part to replace if the relay isn't the issue? Thank you!

[@marianabarajas410]

Thank you for the video, very informative! My 2015 Subaru Crosstrek blows at all speeds but does not blow when changing it to the “feet/lower” setting. Does that also have a resistor or what could it be?

[@dalilahmrtn]

How do check it without the multimeter? What visuals should we look for?

[@paulchatman655]

Hello nice Video! I have a 2010 chevy express 1500, I have replaced the resistor addy and the blower motor. The system works on low, 2nd low, but not the 3rd then works on max after replacement. It also will cut off and then come back on. What would could that indicate failure of? This is all occurring during use of the AC. Thanks for any replies.

[@PulpFictionized]

Would the blower motor be in the same spot for a GMC Sierra 2011 ?

[@johanpepplinkhuizen2413]

Hello thank you for this great video. My problem is still not solved. When connecting power on my car the blower goes for 10 seconds than stops. Doesn t mather number 1 .2.6.or 7. It stops after 10 seconds. After a little time is goed om 10 sec. I used a new motor a other Heather control panel and a new blow motor resister that on the blow motor connected for caching the speed. What can i do now. Hands in my heart. Johan peppl off holland

[@darrelligelmund2115]

I have a 2015 Mustang whose blower works but the heat randomly blows cold, hot, nothing. At first, I thought it could be one of the actuators under the dash controlled by the temperature knob or a fuse, etc. Turned out to be a small leak in a radiator hose. This caused the overflow reservoir to empty. The low coolant sensor that monitors the overflow reservoir then caused my heater to quit working properly. Never thought it would be anything like this. Temp fix is to fill up reservoir. Long term, replace leaky hose.

I have VW Passat 2014, all fans suddenly stopped working, no hot or cold air on any mode. Day before I've noticed that fans were blowing warm air only, even on lowest temp setting. I'm not sure which fuse to check as info varies on forums, or could it be an issue with motor blower / resistor etc ? Thanks in advance

[@MansaMusa-v5q]

This was good only thing I would add is checking the cabin air filter

[@Itzvossen]

This is perfect cuz I have the same truck and I’m having this problem 😂

[@Matowix]

What if it works on 3 and 4 ? Would it still be the resistor ?

[@user-wi1pg5vc3u]

I have a different scenario my car, the relay works i can hear it click there is power to blower as i checked the with multi meter and blower works I checked that separately by pulling it out and put it on 12V, yet I turn fan speed to setting 1.2.3 nothing happens, could it be the resistor but then i should have fan speed on setting 3 right? Can you tell what i have missed it is a Toyota Hilux 2018. BTW this video is very good 👍👍 and easy to under stand hence i am stuck now TY.

[@3.7cadio4]

Hey man I replaced the blower motor and the resistor as well as the fuses and the relay and the ac is blowing at all ?

[@santiagovalenzuela7454]

On my Chrysler 300c the ac/hc worked perfectly until we replaced a ripped coolant hose, after we replaced the hose it doesn’t blow any air. The fans turns on and it turns on every speed level but no air blown out, what can it be ? Please reply!
