chrysler lhs 2001 vents blow only cool air, no heat
Just recently my heater went from blowing warm air, to ONLY cool air. Does not matter what temperature I set the digital control at 75° to 90°, the vents only blow out cool air now. The Air conditioner settings works well, meaning the air cools drastically as the temp setting is dropped below 74°.
The radiator is full, the overflow container has fluid at correct level. The temp gauge never goes above half even on 2 plus hour drives.
Someone suggested that a gate valve, or some sort of shutter is stuck. (is this electronic?) Is this a fuse issue?
Where is the thermostate on these cars located?
Any advice would be appreciated! Thanks.
