I have a 1999 Jeep Grand Cherokee, and the passenger side blows hot air even when the temperature of the dual climate control is set lower than the driver. I have read in forums and many other Jeep owners have the same problem.

(1) no warning (2) cold air coming out of passengers side heater vents all the time, also this makes it next to impossible to defrost the passenger side windshield. (3)I was told it cost $1200 to fix this, and I do not have the money right now to do this.

I'm having issues with broken blend doors and recirculation doors on my 1999 Jeep Grand Cherokee with the dual zone climate control.

Cold air blows from one side of the dash even when you have the heat turned on making defroster inoperable in the cold. This is extremely dangerous in the cold. Dashboard has loud creaking sound coming from its underside when ventilation is turned and creaking from the dash seconds after shutting the engine off. These Jeep are known to have this severe safety issue.

The contact stated the blower fan stopped working and he could not defrost his windshield. At that time, he could smell an electrical fire. The vehicle was taken to the dealership, and they determined the wiring harness for the blower motor melted. He replaced the harness and the resister for the blower fan himself.

Within four years approximately 8,000-10,000 miles both front brake rotors had to be turned twice and then replaced. Also, both front calipers had to be replaced. This causes vehicle to vibrate and make a grinding noise when braking. Dealer and manufacturer were notified, and were unable to locate the cause. The brakes pulsated while driving. The dash vent did not work, and the air only worked through the defrost. The consumer stated the front end of the vehicle felt loose, the dealer discovered the ball joints needed to be replaced. The driver side rear quarter panel was loose

Since puchase of vehicle there has been a vibration when applying brakes. Took vehicle to dealer, and they replaced rotors. Consumer states that recall 00V136/man recall 879 explains the problems vehicle is experiencing, however consumer has been charged for all repairs. After running vehicle with A/C on for longer than an hour, the A/C stops cooling, A/C was blowing through defroster vents, found miscalibrated atc head. Vehicle would cut off at idle. Right rear window inoperable. Crank sensor was replaced.

Brake rotors warped, and subsequently replaced with same quality, thus are warped again, causing severe shaking to front end upon braking. Mfg. Zone mgr refuses to correct situation, stating it is wear and tear, (NHTSA campaign-00V136000). Starter drags intermittently upon starting with a complete failure at 500 miles. Mfg will not replace starter until it completely fails again. Heat is resricted to drivers feet, and high pitched sound is heard as a result of the restriction. Mfg. Tech service bulletin on file for problem, but dealer calls it normal. Remote control memory side view mirrors will not reset to proper positions, thus causing a safety issue, as mirrors are never in the same place twice. Dealer observed problem and disregarded same. Pittsburgh zone manager contacted by dealer. Mgr refuses to do anything, even though safety issues are involved, as with brakes, mirrors, and starting problem.

I am an owner of a 1999 Jeep Grand Cherokee limited V8. I have encountered many problems with this vehicle but some have already been resolved under manufacturer's warranty. A couple problems still exist though. One main problem is that my vehicle occasionally stalls out on me at red lights. It idles very slow (@400 RPM) and this is usually when the vehicle fails on me. I'll lose power to the transmission, but all the electrical items will still work, such as the radio and heater. When the engine dies out, the check engine and airbag lights will display. This problem has been brought to the attention of two dealerships but has not yet been resolved. Another problem I have is that I will feel a big clunk when I am accelerating, usually when I first start to drive off. The second type of clunk I feel is when I put the vehicle in reverse to drive. I will feel a big bang like somebody had hit me from behind. This will specifically happen during the shift from reverse to drive. The third problem I encounter happens when I have my heater on. I will have the control settings set @80's and the air conditioner will operate. I do not have the setting at defrost mode. It is in regular mode and when I want the heat, the ac plus the heat will trigger. I would greatly appreciate it if these problems were looked into. Thank you.

Since date of purchase wipers did not function, air conditioner intermittently fails to blow air for periods up to 30-60 seconds. Can occur repeatedly, with only seconds in between. Overhead computer system repeatedly sounds alarms that the lift gate is open when it is closed. Rear defroster comes on at its own whim, and at times will not turn off unless key is turned off. Transmission was replaced. On board panic system (integrated with the keyless entry system) goes off at will, sounding the horn and flashing lights. Occurs almost continually when vehicle is locked. The body control module was replaced, numerous attempts at investigating the wiring, replacing connectors and sensors have still left us with the defects. The vehicle is well known in the community because it simply cannot be silenced. We have been told that numerous other 1999 and 2000 models of Grand Cherokee have had similar problems, especially with respect to the transmission which has caught fire when it failed during driving (as related by a Jeep dealer service department) we were lucky my husband noticed a problem before it reached the point of no return. Please contact if additional information is needed, will be happy to provide whatever it necessary to begin an investigation into the plague known as the Grand Cherokee.
