Ambient temp display reading wrong
My car was originally never equipped with fog lamps from the factory. When I swapped out my stock front end for the GXP front end I had to find a way to make the fog lamps work. I used a factory fwd lamp harness for w/ fog applications to wire up the front portion of the fogs. When doing so I found that the harness I used had a different connector for the ambient temp sensor. Rather than going through the hassle of swapping the pigtails i bough a new sensor to fit the new harness for $5 and put it in. Here is my problem... since I did this my temp display is about 20 degrees under the real temp. I have searched my owners manual and talked to some GM dealer techs and have not been able to figure out how to reset the reading. Any of you fine people know how to reset the sensor?
