Windshield problems of the 2000 Jeep Grand Cherokee

The driver's blend door, and the passenger's blend door are not working, causing only cold air to come in on passenger and on driver side causing fog build up on the front windshield which prevents drivers vision and could cause a major accident. A known problem by Jeep/Dodge/Chrysler but never had a recall to fix the hazardous and dangerous problem.

Heater and defroster failed to work and nearly caused an accident as windshield would not defrost. Problem was diagnosed to be a blend door failure with failure codes 38,51,54 and 56.

I own a 2000 Jeep Grand Cherokee. The heating works fine on the driver's side of the vehicle, but only cold air blows from the vents on the passenger side. My internet review suggests that it won't be long before I lose heat on the driver's side. This is apparently a very common problem with Jeep Grand Cherokees . . . And Chrysler knows it. The fix is very expensive . . . Blend air door actuator, or something like that. This will become a safety hazard when I am unable to defrost the windshield. Chrysler should recall and fix!.

My Jeep Grand Cherokee was operating perfectly, and apparently the "blend door" or something in the heating/cooling system is messed up. It starts blowing cold air for no reason some times, even to the point of fogging the windshield in cold weather.

I own a 2000 Jeep Grand Cherokee limited with 151,400 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. To correct this problem, a "blend air door" is necessary at a cost of approximately $1,200 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 with duel zone ventilation systems.

Automatic climate control system acts erratically. Regardless of what settings are used, hot air will blow out one side while cold blows out the other. Sometimes which side is cold or hot will switch. I am filing this with the NHTSA because this is a major safety hazard. Because my automatic climate control doesn't work correctly, I have no windshield defroster. We have been receiving a lot of rain lately and the temperatures have been dropping. My windshield keeps getting foggy and I can't clear it. I have to pull over and wipe it off with a towel just to have it fog up again a few minutes later while I'm trying to drive. In the winter, the windshield will freeze over and it is very difficult to keep clear visibility. I can deal with being uncomfortable, but no defroster is a major problem. I have taken the vehicle into a dealership and have been told the cost of repair will be at least $1200. After researching online, it appears this is a very common problem. My fathers 99' Jeep Grand Cherokee had the same problem. Jeep has identified a design flaw and has replacement parts, but they will not fix the problem under warranty unless the vehicle is still in warranty. This is a major design flaw and a major safety issue. Jeep didn't have a fix for this until the Jeep was well out of warranty. I put today's date as the incident date, but this has been happening for the past year. It is considerably worse now and the vehicle will be unsafe to drive this winter.

Only cold air blows from the right side vents on my 2000 Jeep Grand Cherokee. This began the end of this past winter. This problem affects the heat vents and the defrost vent, therefore causes a safety hazard, as the right side windshield ices up. From my searches, this appears to be a big problem, effecting many Jeep owners. My mechanic at the dealership, said it would be about a grand to fix. He also did not even ask me if I wanted to get it fix, almost like it was too time consuming and did not want me to get it fixed. So, therefore I have not had it fixed yet.

Failure of blend doors in heater/defogger of vehicle. Jeep has known about these cheap parts for some time. The repair costs over $1000 because it is labor intensive, the complete dash panel has to be removed to access where the blend doors are located. The part costs are only about $150 at most! with the failure comes no warm/hot air from the heater, consequently no defrosting of the windshield. . . . . . . . . A severe visibility problem!! Jeep/Chrysler should be picking up all, or at least most of the cost of this repair. The original parts were cheaply made and are subject to wear out within only a few years. I recently had to pay for this repair myself. I could not do without the defroster during winter months. I had to pay for it out of my own pocket. I would like to see Jeep/Chrysler refund some of that cost to me, it would only be fair. Do a search on the internet, and you will see the numbers of these same failures for several Jeep year models.

Heating/air conditioning components fail due to faulty components (blend doors, a component known to fail frequently) causing windshield fogging, poor visibility, lack of heat control.
