My 2000 Jeep Grand Cherokee with 90,000 miles has had problems with defrosting and heating for the past year. When it is cold or rainy the windshield will not clear not matter what settings I use. I get snow and ice accumulating on my foggy windshield and I am forced to pull over in dangers conditions and scrap my windows. Recently my heat has stopped working on the drivers side and I looked for information online and found numerous forums with thousands of people having the same problems with their Jeep Grand Cherokee. People have complained for years to the dealership and daimler Chrysler only to be told it was a comfort issue not a safety issue. It is S serious safety issue and I feel this needs to be looked into before someone does get hurt or worse. They are aware of the problem and the dealerships are willing to charge thousands of dollars to 'fix' problems but it should be recalled because they never fix the problem and customers are taking unnecessary risks to drive their SUV's (sports utility vehicles, ironically) without heat, defrost and/or cooling. Please take this complaint seriously and look and see how many other similar complaints you have gotten on the same issues with these cars. I can not afford to buy a new car and I do not want to out myself and my family as well as others at risk because one company is not responsible enough to fix such a blatant safety issue. Thank you

The HVAC system on our 2000 Jeep Grand Cherokee limited has broken and is unable to direct air at the proper temperature to the proper places. The defect appears to be related to electronically controlled dampers in the ductwork that have failed. This prevents our defroster from working as effectively as it should and is also an irritant to the driver when it's 110 degrees outside in the Texas heat. Googling the problem identifies it as a common breakage and is related to the use of cheap plastic materials in the damper mechanism. I believe this should be covered as part of a manufacturers recall campaign.

There is no heat blowing on driver side but heat on passenger side.

- Saint Paul, MN, USA

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.

2000 Jeep Grand Cherokee, passanger side heat does not work - blows cold air - again (10/09)! fixed this once before in 2006 (ish) for approx $800.

- Denver, CO, USA

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.

- Mills River, NC, USA

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.

No heat on passenger side of 2000 grand Jeep Cherokee.

- East Walpole, MA, USA

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.

When heater is on we only get heat out on the driver side only. Cold air blows out on the passenger side. Then no heat from any side of unit.

- El Cajon, CA, USA

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 Cherokee... 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.

The contact owns a 2000 Jeep Grand Cherokee. The heat/defrost function failed in the vehicle. During the winter, the contact must remain cold in the vehicle and the windows become foggy instead of defrosting. The vehicle has been to the dealer twice and they stated that there was possibly a condenser leak in the heater, which caused the control lever for the heating unit to deteriorate. The contact stated that the repair was too expensive. He has found several complaints regarding this failure with the same model; therefore, he believes that the manufacturer should issue a recall. A relay shorted out due to a failure with the heating mechanism and the entire vehicle filled with smoke. There were no injuries. The vehicle has not yet been repaired. The VIN was unknown. The failure mileage was 60,000 and current mileage was 90,000.
