Blend doors on the HVAC system have failed. Passenger side only blows cold air. A common problem on these Jeep.

- Plainwell, MI, USA

Heat stopped working on the passenger side of my vehicle. Now there seems to be little to no heat on the driver's side. I was told that this has been an issue with the Jeep Grand Cherokee line, and yet nothing is done about it. Of course this always seems to happen after the warranty has expired. I have yet to pursue repairs as this will cost me almost $500.

My passenger side heat is blowing cold air and I understand this is a common problem. It has been repaired before and I'm not going to pay anther $900 because its Jeep fault.

The heater blower blows very cold air on passenger side. Very poor defrosting on windshield even with the temperature setting on max.

- Redwood City, CA, USA

Cold air blowing from passenger side vents and windshield defroster regardless of control or temp settings. Driver side temp adjustments work properly, but passenger side and windshield defroster controls do not provide any heat. Windshield does not defrost, as temp mix is not functioning for passenger vents or for windshield defroster. Problem has not been resolved.

I own a 2002 Jeep Grand Cherokee overland with 44,500 miles. The events leading up to the failure of the ventilation system were (1) rapid fogging of front windshield, (2) fogging of front passenger windows, (3) failure of passenger heat while still maintaining driver heat function, and (4) only cold air release on passenger side of Jeep. Consequently, (1) the windshield and front windows do not defog, and (2) no heat whatsoever comes from the passenger side floor and dashboard ventilation system. In addition to the fogging there is a leak of antifreeze, hazardous material, coming into the vehicle driver and passenger areas, due to defective heater core. To correct this problem, a "blend air door" is necessary and a new heater core at a cost of approximately $1,700 inclusive of 7 hours of labor. According to the certified service department at the local Jeep dealer and online forums, this has become a very common problem for 2000-2004 Jeep Grand Cherokee limiteds/overlands with dual zone ventilation systems.

Blend door mechanism broke numerous times, blower motor resistor burnt up twice.

- Roseburg, OR, USA

Passenger-side A/C blend door is broken.

- Ocean, NJ, USA

When heat is on, cold air blows from the passenger side. I believe the passenger side blend door is broken. I believe this is a factory/design problem and it affects the defogger and visibility. Estimates over $1,000 to repair.
