I have a 2002 Jeep GC Limited. My vehicle has dual independent climate control (one for the driver and one for the passenger). For no apparent reason, the heater has malfunctioned. The A/C system works fine for all vents. Regardless of temperature settings, when the heater is turned on, only the driver’s side vent and the 2 vents in the center panel area blows out hot air; the two passenger side a/c & heater vents are blowing cold air. I am wondering is this a major problem that I should take to the dealer to fix. I reviewed the owner’s manual and a Mopar Jeep manual. However, the books do not seem to address this issue. I searched and located a Jan. 2005 post with the same problem; however, I did not determine the actual cause, remedies suggested (1 was given by the moderator I recall) and whether Dpatel resolved his 1999 Jeep GC heater problem. Your thoughts as to the cause and possible remedies for my malfunctioning heater are greatly appreciated. Chuck.
