The air conditioner (ac)/heat do not work on the1999 Jeep Grand Cherokee. The likely problem is the failure of the poorly designed/manufactured blend doors. Estimated repair cost: $1200. I was informed by mechanic that this is a common problem with this vehicle. It is outrageous that such a system would fail so often and cost so much to fix.

I own a 1999 Jeep Grand Cherokee ltd, also referred to as wj. In the 2 years I have own this Jeep certain problems came up. Apart from the issue with the front brakes warping the rotors, and needing upgraded calipers and new rotors replaced. Which the DC dealers didn't want to acknowledgments other issue and equally troublesome and probably dangerous is the current issue of the HVAC system no working properly. This problem is very common amongst these vehicles. I have a little heat blowing on the driver side compartment, but 0 heat and all cold on the passenger and defrost. God help me if im stuck on the side of the road during the winter, which it is right now. My passengers and I would not fair well. The cold blowing from the pass. Side vents and defrost is like the A/C was on. Now, this issue is the blend doors are broken, Chrysler and Jeep both now of this issue. And the cost of the repairs of course are very high from the dealership, as it involves removing the dashboard the center console and the steering column. This has to be a recall and fix their expense at least.

All four brake rotors wore out excessively which has caused vibration in steering wheel when applying brakes. Brake rotors have been resurfaced every ten thousand miles. Consumer has contacted dealer, and dealer has turned the rotors. However, problem still occurs. Consumer states air conditioner was not cold enough.

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.

Repeated problems with ac/heat being erratic, will take vehicle in for 4th time. Vehicle shuddered, fixed by changing fluid. Weather seal fell off. Brake shudder fixed by replacement of rotors, etc. Engine stalled fixed, but the rev up and lurch at stop is not yet. Setting another appointment with service.

Air conditioning does not cool. We have had it to the dealer 4 different times and they have not been able to fix the problem. We were told there is a vacuum leak somewhere. The dealer has added different parts to aid in the vacuum, but nothing is working. This problem has affected the use, value, and possibly the safety of the vehicle.
