I had an accident in the winter of 2008 and after the accident i found out that my thermometer was broken and the car was not running at proper temperature. After a while i started to notice that the heater was not working as it used to. The car would not warm up at more than a luke warm temperature. After I got the Thermometer fixed the cars heater worked as well as it used to and it would once again get hot enough to make you sweat on the coldest of days.

Thought I was being too picky that my heater doesn't seem to get very hot until i heard a couple people talking about the same problem a few days ago. I asked them what kind of cars they had and they said Pontiac Grand Prix and one had a Pontiac Grand Am. Curious if there are others out there with this same issue and if anything can be done to correct it. I have to run the heater on full blast all of the time in the winter, and also have to run the A/C full blast all of the time in the summer.
