I have not had any heat in my car for a few years. Usually not a problem. It would be nice if it worked.

Today I removed the plastic cover that protects the motor that opens and closes the door which mixes hot and cool air to the desired temperature. With the car on, the door did not move when I turned the dial to "mix" the air. The motor didn't appear to be receiving any power, or signal to move the door.

Any suggestions on what may be the problem would be appreciated.

Thanks, Adam

 

rear wiper fuse ok?
rheostat (adjustable temp ****)?
hvac controler

 

Rear wiper fuse is good (I don't have a rear wiper).

Temp **** moves properly and is seated correctly in dash.

Don't what you mean by hvac controller. AC works fine.

 

Any other suggestions?
