Defogger problems of the 2004 Jeep Grand Cherokee - part 1

Dual climate control blend doors have broken, a defect in design that affects all 1999-2004 Jeep Grand Cherokee limited models. There is no hot air available to the passenger side of the cabin, and the passenger climate adjustment is inoperative.

The hvac system of the 2004 Jeep Grand Cherokee (dual climate zone) fails after a short period of time prompting expensive repairs. The hvac system will blow ambient outside air on one half of the car. If it's hot outside, hot air, not ac, will blow on the passenger side. Cold air in the winter.

2004 Jeep cherokee blend doors. I have to use a towel while driving to wipe the interior windshield since my defroster has gone bad. Why does Chrysler not cover this as I consider that to be a major safety issue.

1. My air conditioner started acting up and not blowing the correct hear/air. 2. The blend doors are broken on my Grand Cherokee 3. Nothing yet, its a $1200 fix.

3rd failure of climate control system inside vehicle controlling a/c, heat, vents, etc. Have paid a total of $3119 to have it repaired with new oem Chrysler replacement parts by certified mechanics. The same failure continues to occur where the climate control "blend doors" break in their plastic housing causing the doors to move independent of the computer control signals. In the winter, cold air will blow regardless of setting, and in the summer hot air blows - also regardless of setting. This latest failure occurred outside of the warranty. It was already fixed once within warranty period before 2 subsequent failures. Dealer reps informed me that 80+% of vehicles with dual climate control option have this problem. I have owned a 2000 and 2005 Grand Cherokees and have also experienced the same issue with both vehicles.

The door blend and actuators have failed on my Jeep. Middle of winter and my passenger has to sit in a vehicle with cold air blowing on them.

Heat and air conditioning died in my 2004 Jeep Grand Cherokee overland, it only has 60,000 miles on it and I did some searching online and this is a common problem for the 99-04 Grand Cherokees. I live in a cold weather region and cannot defrost my windshield making it quite dangerous. It will cost $1,200 to fix it and I cannot afford to pay that. Chrysler is saying it is my responsibility to fix. But the problem lies with the blender actuator doors being too cheap when built.

It usually goes back to normal cooling after about 2 hours or so.

2004 Jeep Grand Cherokee with defective heat and cooling system. Consumer states that after about 30 minutes the heat on the passenger side is replaced by cold air.

I do not know what caused the problem, but the blend air door on my 2004 Jeep cherokee is broken and only blows cold air. The air does defrost the window or heat the cabin. This could lead to a driving problem if the windows fog up while driving.

Climate control started blowing nothing but cold air out the passenger side vents. Not warning preceded the failure. I just got a complaint from a passenger that they were freezing one day. Research lead me to find it is a poorly designed blend door in the hvac system of wj Grand Cherokees. A quote of over $1000 to fix a cardboard part!.

Jeep Grand Cherokee limited 2004- heat not working properly due to blend door misfunctioning. Spent $1200 at Jeep/Chrysler dealership to fix and less than one winter later it is broken again. Even replaced all parts t-working and non working parts. This is a major problem with Jeep and this should be made a recall. Thousands of others are in our same boat and there are forum set up just on this issue. This is too much money to spend every winter on the same malfunction! drove less than 10,000 miles in 12 months on my vehicle. This should not have recurred.

Defroster/heater does not work on 2004 Jeep cherokee.

There were no events leading up to the failure that I am aware of. I attempted to use the heat this past winter, and nothing would blow out. No heat, no air, no defrost. My windows will not defrost. I took it to the dealership and they diagnosed it as broken blend doors. Needs blend door housing. They were asking around $1,000. 00 to fix it. I researched this problem online and found a forum where many people were experiencing the same exact problem with the same model. This is a factory defect. Nothing has been done to correct the failure. I don't have this kind of money. My vehicle was only 3 years old. I contacted the manufacturer to no avail. This summer I , along with many others, will have no air to keep them cool.

Heating and a/c malfunction, blend door actuator broke, messes with the flow of the heat and air. I've heard it happens to all these Jeeps.

Passenger side heat does not work in our 2004 Jeep gr. Cherokee. It is related to a door within the climate control system. It sounds like there are many people who have had the same problem with this. Estimated cost to fix is $800-$1000. The windshield will not defrost because all that blows is cold air. This is a safety hazard that needs to be addressed. Daimler Chrysler needs to be responsible for these defective parts.

I am having a problem with the steering, brakes, and the heat vent. When turning left or right, it makes this awful noise. When applying the brakes, the steering wheel and the front end begins to shake. I took the vehicle to get the brakes changed and they said the pads look fine. When I had the heater on, it was blowing cold air on the passenger side.

The contact stated that the blend door on the front passenger side was defective. The door prevents heat from entering and causes the defroster to work only on the driver side of the vehicle. She took the vehicle to a repair shop and was informed that the failure was due to a faulty blend door. The vehicle has not been repaired. The failure mileage was 48,000 and current mileage was 52,000. Updated 10/24/07.

The first vehicle is now broken again, which will cost another $1500-1700 to repair for the same issue.
