HI Jim you were great on explaining how to check for a burnt out motor when the blower or heat doesnt work I will check to see if the motor in my car is not working because the heating system doesn't do anything. I was told it might be thermostatic or resister. You are so patience when showing the problem. Thanks very much

Nice! Got a burning electronics smell from the vents and the fan motor quit today.. so, looks like another motor on the garbage heap! Also, have been through the blend actuator motor FOUR TIMES on 3 of these Mercs! Now I just use a 9v battery and connect to the purple wire from the controller and run the blend motor to hot for winter and to cold for summer and leave it at that, works beautifully and takes no more than 5 minutes to do after the first time. Clip the purple wire and connect + 9v battery to it and - to ground for cold. Reverse - of 9v battery to purple and + to ground for heat.. run either way until you get the telltale clack clack clack of the motor hitting its' end stops.. DONE!

I had an issue with my dad's truck (F150): His blower motor wasn't working, he had power to it and it still wasn't working. So i changed it and it still didn't work. I did a deep dive on youtube and found the blower motor has a resistor that acturally sends the signal to the motor from the dash control on when to come and what speed to run. After I install the resistor the motor worked fine. Thanks.

[@ImparableEM]

The ac/heater went out on my 2004 CV. Tested the blower motor by connecting it directly to the battery and it worked fine. Did the Blower Motor wiring test with the control module on, and it didnt show a - but did show a + . Before messing with the wiring I replaced the Resistor and that solved my issue. Resistor didnt smell burnt, damaged or anything but took a chance and replaced it anyways. Issue solved. Good luck guys!

Maybe you can help. My blower motor was only blowing on high. I replaced it with a new one, same thing, high only. So I guess I need to replace the blower motor control module, is that correct?

The thermostat is opening and full of antifreeze. Can you tell me what to do know? It's getting cold.

Hi sir, i believe i have a different problem. I have a 2011 crown vic, manual AC control, i would get in car to drive and no air coming through registers then go into store come back to car and boom the ac works again. The AC is working but blower motor not working, this is off and on. So someone suggested i replace HVAC blower motor resistor, which i did, but yet same problem. I would appreciate any advice , thanks.

[@richardjohnson1427]

Hello Jim. I really appreciate your video's. My sister has a 2010 Audi Q5. The blower motor stopped working. It does not work on any of the speeds. I am thinking that the resistor is most likely the problem, but not certain. I am wondering if you have every changed a blower resistor on an Audi Q5? I have purchased a few different repair manuals for this vehicle, but they are useless. It seems like Audi has refused to release any repair info fro this vehicle. Any thoughts or advice that you can offer would be very much appreciated! Thank you. Richard

[@mauricematthews5065]

richard johnson Basically if you are getting no response from either of the speeds of the motor blower, most of the time the motor needs to be replaced, but first do the exact same thing that was done in this video, check for power and ground in the wire harness going to the fan motor first.

[@antknee6579]

I'm a little late but I'll try for answer .. 2003 ford CV blower motor or not? not blowing high or low ....took out motor jumped off battery spins fine I guess lol or is it the resistor ? i heard if it blows high only its resistor but its not blowing either fuses sre fine also...resistor? lol

[@BajooJajoo]

I hope you read comments. I have the same car but my air won't turn off. The second i turn my ignition to give power to the car, it starts running on high. I can't turn it off by pressing off, and i can't change the speed of the fan, only the temperature. Will getting a new motor with a resistor fix it? Or do I need to buy a new relay?

[@lancedrexler2748]

I have similar issue. For you I would check your compressor and make sure it engages as well to be sure. My Jeep has no air or heat on any setting. I tested the blower motor with test leads to my battery and it turned on really strong, compressor engages how it should, I can also hear the blower motor and vents engaging inside the cabin, and it's full of freon. The last thing that I have is the resistor that could be bad and that's all that I have left to check other than a possible relay. Good luck hope you found your solution and maybe this helps.

I have a 2012 Ford Focus that got the ac system completely discharged after replacing the engine. Now I have no air at all. Friend of mine tested the Blower motor and resistor and he said they are in working condition. He claims since the ac system is empty there's a pressure switch that will not allow the blower motor to engage. Does that sound correct? Sorry for the long comment. Great video btw.

[@jimthecarguy]

Does the fan turn on but blow out warm or do the fan not turn on at all? The ac being empty will cause the ac compressor not to turn on but the fan should still blow out warm air. Keep me posted.

[@pedrodelasancha516]

@@jimthecarguy Hello there, thanks for the reply. No, the fan does not turn at all. However, I did the following tests. Checked the relays and fuses, and they work. Checked the resistance in the Blower Motor Resistor and it checks out to specs. I provided power directly to the blower motor fan and it turned right up. And one last thing, I checked the blower motor resistor input wires by probing the hot wire in the connector with a test light to see if they were getting any ground when the HVAC switch turned on. Here's what I found. When I set the switch to speed 1, the wire corresponding to that setting gets grounded. When I set the speed to 2, the wires for 1 and 2 get grounded, when I set the speed to 3, the wires corresponding to 1, 2, & 3 get grounded. And finally when I set the speed to 4 (Max), all the wires in the blower motor resistor connector get grounded. I saw in another video a gentleman saying only the wire corresponding to the set speed should get grounded. Is that correct? What could be the culprit? The HVAC Switch? Thanks a bunch for your help, in advance.

[@n1kkri]

would the procedure be the same for a 2003 Grand Marquis? Mine quit. I can measure 13v at the connector. If I change the fan speed from the inside it changes the voltage at the connector which I assume is how it changes the fan speed. I also applied 12v from the battery directly to the fan and no go.
