- HOW TO TEST HEATER BLOWER MOTOR FAN. HEATER AC FAN NOT WORKING FIX
If the heater blower motor fan is not working on your car we will explain how you can test the heater blower motor fan in just a few minutes and figure out if the cause the heater blower motor fan not to work is bad motor or you need to look somewhere else. The heater blower motor fan is also known as HVAC blower motor fan, air conditioner blower fan and more. We demonstrated how to test the heater blower motor fan out of this Dodge car that we work working at the garage. The reason for the heater blower motor fan not to work was not the motor itself but it was a bad relay. The procedure to test heater blower motor fan will apply to most modern cars using 12v system.

My fan stopped blowing completely. I took it out and while it was still connected, I turned on the AC and nothing, but I can hear a little click, so I knew it was getting power. So I Spun the fan manually and used a brush to clean around the spindle. Reconnected it and it’s working perfect. Worth a shot before replacing it
You are a very good technician thank you for making it easy for us to understand great demonstration👍
Man, yer videos are very easy to follow, and learn from. I like how u don't "talk" down to the viewer's and just explain in theadiest way to understand! Thanks for making them!
Quick and to the point good video
Thank you so much Misha. You saved me bucks. 🙏
.. Thank You .. EXCELLENT DEMONSTRATION .. EXCELLENT VIDEO & AUDIO QUALITY .. 1ST-CLASS ..😍👍🙏
Good nigth! My name is Leidervan , your videos are good. I have a car fiat freemont. I live in Brazil and I watch all. I learned many things with you are fixing that Journey. My ligth of stop is sad, what I do?
Thank you. Now i want to test my old one to see if it was still good after i put in a new one.😅
Hi if the ohms are reading high does that mean the motor is bad? It read as high as 100 then goes down to 5-6
very nice video. can connect to test without turning engine. test any poison smell, as when engine on could suck from broken exhaust pipe poison gas inside the salon.
spot in
Tested the voltage for the blower motor with switch turned on high and was only reading 5 V, any ideas?
If I check the blower motor outlet and have ground and power does that mean it can't be the temp. control switch? I replaced the switch a few months ago and I'm just trying to rule out that being it. Thanks in advance
I did this with my car electricity on (not started) and it just kept sparking. Should this test be done without the key out of the ignition? (no power)
My rear hvac stopped working in my 2019 chevrolet traverse and both wires are hot is that normal? No ground.
How about the resistance? How you can find out ?
Hello. What can be the problem when heater fan is always on?
U forgot to use a table, but thanks it helps me a lot
You do not need a table for this install.
2008 Audi A4 2.0. Ac will not blow either on hot or cold. I do not hear compressor turning on. I have 12V at my wire going to my 5 pin relay but my 5 pin relay ohms OL on every pin. Also my Fan ohms OL on every Pin! Either both are bad or my meter is junk. I feel like I'm at the end of the circuit becaues I have 12V at relay wire and the only thing in between is the relay I think is bad and then to the fan which I think is also bad. Also applied 12V to my fan and nothing so that confirms one is bad. Still wondering about the relay. Fog lights and compressor don't work and I suspect that the 5pin relay if its bad is controlling not only the blower motor but the compressor and fog lights. Am I on the right direction? You said more than one thing could be bad right?
Bench testing is for beginners and still useful but testing before removal is more helpful and some models have blower motor resistors which sometimes fail before motor. Just saying.
Hi,
My cars blower motor resistor is keeps failing while trying to replace with a new one. Could you please suggest a solution?
What if it has a bad armature wire winding?
I have a 2015 Opel Adam.
My blower motor stays on all the time even if the car is off and keys are out
Hello sir chevrolet Cruze problem driver siad no working heat colling ok
Busa 🏍
What if the resistor still working but the fan power is weak ?
Yes ,, same question ,, you only checked if whether is working or not ,, but the real checking is how power rotating it is .. is it powerful as new or aged used ..
Just because it spins does not mean its a good motor, I had a problem with burning blower motor switches. I checked amp draw of the motor and it was pulling roughly 250 amps. No wonder the switches burned. Voltage drop tests didnt really tell me anything, i was dropping about 1.5 volts on the positive side. And had .6 volts dropped on the negative side, understandable since for 250 amps 14 awg wire is not even close for such a draw, thus creating a substantial voltage drop. Strange thing is it never popped the 40 amp breaker, im assuming because the blower switch was acting like a resistor limiting amp draw. Hope this helps someone.
Im having a problem in my car I just a bought and brand new blower motor after having the same issue as you changed the relay, resister, and blower motor and the fuses keep blowing everytime I go to turn my ac on what should I do?
My blower motor com on sometimes and not com on sometimes by it self.what can be the problem?🙃
Having the same problem did you ever figure it out?
@@jasmineprice2645 Can be the blower motor or the resistor on my car it was the blower motor.
@Noyesv thank you
What did he say???
Guys
step one, buy at $70 dollar battery
You had everything u needed to measure the current draw, and you skipped it. Bummer.
Stop saying GUYS pls. Lots of women mechanics out there too.
Just hold the motor with one hand and bang 12v on it to test it . Why you saying it dangerous.?? Face it away from you and hold it with one hand or position it into a vice
Hardly rocket science
You're telling ppl not to do it because it dangerous but showing us ?? Strange video 📹
Such a fake accent
