My 2001 Jeep Grand Cherokee with electronic dual climate controls requires major repair in order to cure hot air/cold air blowing from vents when they're not set to do so. The cost to repair this issue, which has been known to pop up again after another 50K miles after repair, is generally $800-$1500 from a dealership. Should I opt to do this repair my, the entire dashboard will need to be removed, quite the arduous process, and parts are approximately >$300.

My 2001 Jeep Grand Cherokee heater/ac blend doors are stuck. I cannot defrost. This causes dangerous situations where the wind screen is fogged, and I cannot see the road.

Cold air blows out of defroster vents, even when setting is turned up to high heat.

Windshield defroster failure.

Front windshield and passenger side windows fogging. Ac making lots of noises. Smell of coolant inside vehicle.

There was no heat on passenger side due to blend door failure. Therefore defrosting the windshield properly was not possible. This was followed shortly by a leaking heater core which filled the car with coolant mist during vehicle operation. The blend doors assemblies were replaced along with the heater core to solve the problems.

The defroster doesn't work correctly due to the blend doors failing to open when needed. I see this as a very dangerous safety issue in cold/icy weather here in new england. It seem to be a common problem after speaking with the Jeep service people and other Grand Cherokee owners.

My heater and defroster does not work. This is known problem related to the blend door failure with Jeep Grand Cherokee with dual climate control. This is very dangerous in icy weather.

Heating system worked fine until warm air suddenly stopped blowing out of vents. Took the vehicle to the dealership and they said this was a common problem that they probably do about 3 or 4 a week. Total repair bill was $780. I didn't have this kind of money and it apparently was never recalled, just tsb. It has been two winters now driving with extremely fogged windows due to no heat. Jeep has done nothing to help with this huge expense.
