SOURCE: Heater only work on high

Most likely is the resistor when they fault the default to high giving you off and high only

SOURCE: Heater Control Switch Only Works on High

I have a 2001 Chrysler Voyager and had the same problem. I found a fan blower resistor for under $20 and replaced it in under 20 minutes. I made a video 'how to' and hope you find it helpful.

Have a 2009 Nissan Quest I can't turn the heat off. Just stays on a high level of blowing out heat .


If you have a fan that has different speed settings (1234, or low med high etc) and the only one that works is high - then the blower resistor pack has failed. If you have a climate control unit (where you just pick a temp you want) then the fan is controlled by the heating system and it sets fan speed. If you have climate control style try lowering the temp to a lower setting (current temp in vehicle) and see if fan slows down. If not then climate control unit or fan resistor bad. If dial type and you get nothing on lower settings (only high works like mentioned above) you need to change blower resistor. It is located under dash near the fan itself. Look for small unit bolted in duct near fan with wire plug going to it.

Why wont my a/c or heater fan come on?


When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

Blower motor is stuck on high. i have control of the a/c and the directional funcion. no control of the heat side or off and on. its automatic climate control, and the display is now blank. i have changed...


If the blower motor only works on high mode, then its problem with blower motor resistor. ------------------ The blower motor resistor needs to be replaced.This will make blower motor work on all modes. ----------- Thanks.

Replaced the climate control and blower wont work


f that just put power to the blower moter and see it it runs if you pull the relay jump a wire across the terminals with it out and add a ground wire to the case of the blower to another spot on the chasis if it still does not run your blower switch may be bad dont worry just run a toggle switch to a good blower moter

Blower is on high all the time. Seems like the climate control system is not working. Didn't know if there is a blown relay? or a bad sensor?


No none of the above. There is no sensor for the blower and if the relay for the blower motor was blown then the blower won't get voltage hence wont turn on at all. Sounds to me like the climate control is shorted and is not allowing variable resistance to chance speed. Good Luck

Blower fan does not work on low or medium only on high. Lx model has auto climate control. wondering if it is blower motor, blower resister, or control (bad contacts). All buttons work on climate control....


Sounds like the problem is more with the blower motor assembly itself. The blower motor have micro-proccers built itnto them which comunicate with the control heads and do the actual regulating of the fan motor. Dealers have computers with diagnostic software which allows them to monitor what is happening in the eletronic controls of the vehicle. Electronic diagnostics without the diagnostic software makes it very diffecult to pinpoint the actual item causing the problem.
