I need the part numbers for the 2008 HHR SS for the outside temp air sensors.

I know there are two to replace, but can't find the 2 part numbers.

They replaced one today, did not do any good still don't work.

Any help on this issue ?

 

TWO? DIC temp & mirror ?

 

The dealership also replaced my temp sensors on my 2LT HHR as well, and it made NO differance either. My temp gauge is off at least 10-12 degrees all the time.

 

If you are talking about outside ambient temperature sensor there is only one. Usually replacing it does not fix incorrect temperature readings. This is normally a BCM problem.

 

And where is it ?

 

BCM (Body Control Module) is the all mighty computer that does all the thinking and performs all the wonderful functions for your HHR. If you are under warranty take it in and they will either reflash or replace it.
