I have a 2001 Intrepid. Both the heat and defrost worked like a charm a few weeks ago, but now when I start my car, it justs blows cool air even when the car engine heats up to normal operating temp. When I start driving, there is no problem (both heat from vents and defrost work fine), but when I am stuck in traffic, it will again start bowing cool air. Do you think my blower fan is the problem, or do you think it could be the heater coil?

P.S. I also had my A/C system replaced in August (compressor, expansion valve, and accumulator)... I doubt the problem stemmed from this, but I just wanted to cover all the bases)
