Asked by Feb 01, 2016 at 09:18 PM about the 2003 Chrysler 300M STD

Question type: Maintenance & Repair

My girlfriend has an 03 Chrysler 300. The other day
we were driving and the V-belt broke. It got
replaced and we the heat gets turned now the car
wants to die and make a high pitch noise again.
What might be the problem?

Might be air condition compressor seizing up.Air compressor works with the defrost.Best thing, is to take belt back off and check all the pullies.They need to spin free.

Locked up A/C compressor is my first guess, when you turn on the heat it turns also to dry the incoming air to help with moisture on the Windows.
