I have a 2002 grand cherokee overland. I realized my heater vents on the passenger side weren't working after the vehicle was beyond the 36,000 mile warranty. I believe the failure was long before 36,000 miles but it was too late for the problem to be covered by the warranty. I took it to a dealer who told me the vent-air door had failed. The cost to repair was quoted at being around $1300. I thought it strange that a failure of this type would occur especially in a vehicle with low mileage. I haven't got the vehicle repaired yet but it is certainly an aggravation in the winter. I talked to two people where I work who own grand cherokees and both their jeeps have the same problem. Seems like an unusual coincidence. After checking on the internet it appears a lot of jeep owners are having the same heater-vent door problems. Sounds like a design problem to me that jeep owners are paying the price for.

The dual-zone climate control on the jeep grand cherokee overland stopped working. The 2 vents in the center of the dashboard respond to the climate control settings, and blow the appropriate temperature air. The remaining 3 vents in the dash, and 2 additional floor vents only blow air that is the temperature of the outside air. , in the summer time, 2 vents blow cold air, and the remaining 5 blow hot air. And in the winter, the opposite happens; 2 vents blow warm air, and the remaining 5 blow cold air. This was my second grand cherokee that has had this problem, and my brother's grand cherokee has also had this same exact problem. Upon speaking with dealers, it seems like hundreds of trucks need to have this identical issue fixed. It was related to the blend doors, which ere part of the dual zone system.
We own 2 jeep gc laredos, and have had 3 window regulators fail in the last 3 months. The loud pop and the window dropping each time has almost caused crashes. While this wa s not currently a huge safety issue it was definitely a major design fault and jeep should act on it with a recall. Also, like most people we had warped rotors and brake problems from the start , 3 times for the jeep and 2 times for my husband's jeep.
I own a 2002 jeep grand cherokee overland. E events leading up to the failure of the ventilation system were (1) fogging of front windshield,(2) fogging of front passenger windows, (3) failure of passenger's heat while still maintaining the driver's heat function, and (4) only cold air released on passenger's side . Consequently the windshield and front windows did not clear. Whatsoever came the passenger's side floor and dashboard ventilation system. To correct this problem, a blend air door was necessary for apprately $1,200. 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 cherokees with duel zone ventilation systems.
Air conditioning subassembly blend mode doors are not functioning properly. When the air conditioner is on, air will blow on the driver's side but not on the passenger side.
Ventilation system failure, cannot use defrost to see out windshield when fog appears.
Hvac system died, blend doors and recirc doors located under dash have failed, this is a common problem on this vehicle, $2000 to fix, chrysler should recall this problem as every grand cherokee experiences it. So until fixed no ventilation, notable defrost so windshield fogs up causing unsafe visibility.
The heating/air conditioning system on 2002 grand cherokee was faulty. The vehicle has just over 65000 miles on it. I just had it repaired at a cost of over $1000 and it was still making noises that lead me to believe it will fail again. It wasnacceptable that a car company with as much experience as daimler chrysler could not design a quality heating / air conditioning system.
2002 jeep grand cherokee - broken "heater blend doors". Internal failure resulted in approx. $850 repair. Research has shown that this is a common failure for this model jeep. Four dealerships told me that this "happens to all 99-04 cherokees" and that jeep has not been willing to issue a recall.

Complete failure occurred sometime in march 2007.

About 3 months ag, the blower started blowing out cold air on the passenger's side. Just figured out what was wrong and going to try and find the part and fix it.
Bad design/material of HVAC component , blend door, causes part to brake, which then does not permit heated air to defrost passenger's side of front windshield, ice builds up on windshield, causing poor visability.

I own a 2002 jeep grand cherokee limited with 58,400 miles.

Consequently,(1) the windshield and front windows do not defrost, 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.

Visibility: defroster/defogger system:windshield:blower blend doors and recirculation doors no longer function. To my knowledge, this is a design flaw and will affect every 1999-2004 jeep grand cherokee with auto climate control. The dealerships request a ridiculously high price for repairs. Jeep/chrysler should step up and correct this malfunction in their faulty product.
