I have a 1999 Intrepid ES, 3.2, with climate control. Lately, I've noticed that I'm only getting heat when I'm moving or if I increase the RPM while idling by pressing the gas pedal. When I stop the car and it's idling, I get ice cold air coming into the car. This will occur whether the climate control is on auto or manual. Can someone give me a tip as to the cause before I take it in for service?
Thanks in Advance SE
