Defroster/Defogger/Hvac System
On my 2002 jeep grand cherokee limited with only 55,000 miles, the defrost / heater does not work properly. From my limited research, it appears the blend door for the dual climate control is an issue for many jeep owners. Note: does tsb 2041004 apply to this issue? *nm

Started the car and one day the heater just started blowing cold air. Never made any noise or anything but slowly the passenger side stopped blowing hot air then the driver side and even the windshiled. No repair has been made becuase of the cost ranging from 1,000 to 1,500 dollars. New parts need to be made free of this defect and manufacturer should cover the cost of repair to every owner in which it occurs. *nm

1) rapid fogging of front windsheild,(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 windsheild and front windows do not defog, and (2) no heat whatsoever comes from the passenger side floor and dashboard ventilation system. To correct this problem, a "blend air door" is…

No heat on the passenger side. Windshield fogged up on passenger side. Defroster didn't work. Greasy substance on inside windshield and windows. Diagnosis: shaft on blend door broken ie. No heat. Replace shaft & door. Expensive. Heater core had to be replaced - very expensive. Had to go in through the dash for both repairs. Jeep not interested in talking to us about these problems. *nm

A/c system blows cold air only due to high failure item known to daimler-chrysler. Results in no defog during cold weather unless you want cold a/c blowing during the winter with sub-freezing temperatures. Problem can be eliminated if you buy a jeep grande cherokee in tropical climates only.

I own a 2002 jeep grand cherokee limited with 51,474 miles. I purchased this as a used car on nov 30, 2006 from a reputable (?) dealer. To my mistake, we did not check out the heat. We do live in south west fla. Upon needing heat to take the dew off my windshield i found i have none. My windshield and side windows do not clear on mornings that heat would help in that situation. It is extremely dangerous as you would…

My jeep grand cherokee's ventilation system has a fault component which causes the vents to blow all cold or all hot air. It causes my windshield to fog up uncontrollably. The repair should really be the product of a factory recall, instead, it will cost me approx $1400 to fix this problem on my own. I know this is a major failure point on these vehicles from 1999-2004. It is a major safety concern and i am willing…

2002 jeep grand cherokee - climate control blend door failure. The passenger side temperature blend door failed at 53k miles. This is a known problem with all jeep grand cherokees. The failure was repaired under a self purchased (i.e non-chrysler) warranty with a $250 deductible. The warranty company would not repair the drivers side bend door, thus this repair will most likely need to be performed again. *nm

The car does not blow heat on the passenger side. Apparently there is a well known problem with the blend doors and the actuators. It is very dangerous in the winter when the right side of the jeep does not defrost because no worm air blows out. No visibility. *tr

Defective hvac blend doors on jeep grand cherokees from 99-04. Under normal use these blend doors fail and require a $1800 fix that requires total disassembly of the interior of the vehicle by a trained dealer mechanic. In order to have adequate heat and cooling in my vehicle i had to pay to get it fixed. *nm
