    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

    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 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

    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

    2005 Pontiac GA blower top speed failed. Then,shortly after other four ceased. Replaced resistor and then blower motor without change. Checked fuses and even swapped the starter relay with one for this and Still nothing. Frustrated. Anybody? I realize both new parts could be defective but betting against. And this vehicle has a few quirky electrical issues. Has had for few years. Electrical overhaul? LoL

    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?

      If this voltage going in to the motor (power connector) - its High R on power side.
      If this voltaje comino out of motor - ground sid R

    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.

    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 📹
