Air/Heat Stopped Working After Battery and Belt Replacement

Asked by PassRusher Jan 06, 2021 at 04:43 PM about the 2007 Chrysler 300 C RWD

Question type: Maintenance & Repair

We have a 2007 Chrysler 300 that we recently had a battery replacement
and serpentine belt replacement on. Since then, both the heat and air
stopped working. It just blows air but doesn't cool or heat.

What could be some things to check to get it working again? It worked
perfectly fine before this.

1 Answer

Update... I tried pulling fuse 41 for a few minutes and putting back in. No change. When I do turn the air on, I hear the compressor kick in but just doesn't blow cool air. When running heat, I turn it on FULL HOT and it just doesn't get hot...EXCEPT for the blower for the back seat, which gets really hot. Not sure what else it could be especially since it was working perfectly before.
