My climate controller works when it wants to

When I turn the car on and turn the heat on, the fan will not kick on.
I turn it of and on and nothing, than after driving for awhile try it again and then it works.

To test your fan motor open the hood and test the tabs manually and bypass the climate controls. there is a ground and a power(purple wire IIRC) take some wires not too big and just jump those tabs. if it works then you have other problems. also check for rust or corrosion on these tabs. very common since its under the hood. clean tabs and connectors. if the motor is not working when your trying to jump the wires then you have a bad blower motor.
Good luck

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.

climate control requires the ac to work as well to vary the heat temperature and remove humidity from the cabin air. Check that the ac is working .

Only my passenger side fan activates at about 197 degrees according to the climate control diagnostics. The driver side fan never activates. Is this a malfunction? My temperature gauge gets awfully...


I don't know the specifics of your car but one of my cars has two fans but one only operates when the A/C is switched on. I don't know what you are referring to with climate control diagnostic? That same car of mine almost gets too hot before it kicks on. Maybe someone with a car like yours could answer that.
