Hi everyone,
I am having trouble with the heating in my 2004 Pontiac Grand Prix, and I am not sure what?s causing it. The heater either isn?t blowing hot air at all or only gets warm for a few minutes before going cold again.
This started happening recently, and I have already checked the coolant level and it seems fine. The engine temperature gauge looks normal too, so it doesn?t seem to be overheating.
Has anyone dealt with this before? Could it be the thermostat, heater core, or something else? I would appreciate any advice or suggestions on what to check next.
Thanks!
