as long as the engine temperature is normal, i would suspect a clogged heater core, the dex-cool antifreeze is notorious for building up deposits in cooling system. have heater core flushed first to see if it makes any difference

I have and 98 Intrepid 3800 motor, and had same problem.
I tried a few things, but what finally worked was when I took the car for a complete cooling system flush, they opened the radiator and cleaned every single passage line, flushed motor and heater core,
It cost me about $100 but I havent had a problem since. I recommend you do the same.
There is a screw on the thermostat housing that is used to purge the air out of the cooling system. On your owner's manual are detailed instruccions of this procedure.

Press the auto button, spin the temp control knob to 60, and make sure the "ECON" button (if you have one) is NOT on. The freon will need to be charged enough to cut the compressor on.
