I have a digital dual climate zone in my vehicle. Recently the heat started to work only on one side (drivers) and not the passengers. After researching the issue, it looks like there is systemic problem with the mechanical recirculation and ventilation doors for the heating/cooling system as I found many complaints online with many who have had the same issue. In addition, I called a dealership with the problem codes that I got from running a diagnostic test via the heating/cooling control panel and the dealership also told me this is a very common issue and that it would cost a minimum of $800 to fix. The price to repair was consistent with what others were saying during my research. This is a safety issue as if I have not heat I can not defrost my windows in the winter.
On are 2004 Jeep Grand Cherokee overland with automatic climate control the blend doors have failed and this causes the hvac unit to either blow hot or cold when turned on but you have no control of it. We have had the a/c kick on when unit was set to heat/defrost in the middle of winter and this causes a safety issue as the windshield will start icing up or fogging up if it's not real cold out and as my wife drives this vehicle daily I want her in a safe vehicle. We have also had the heater kick on when using the a/c and all you can do is turn the hvac unit off and roll down the windows. From what I have been told all Grand Cherokee's have this problem just at different intervals. I know some people who have had multiple failures of this part. To get the repairs done at a dealer we were quoted $950 to fix it but I believe Jeep should be looking into this as it is such a common problem and it causes a major safety issue during the winter months if and when the heater/defroster quits working. When the hvac system gets stuck there is nothing you can do to fix it sometimes it will stick for a few hours other times it will not work for a day or two.
Heater and air conditioner does not function properly. May blow heat on one side and cool air on the other side when the a/c is on. Â may need to turn all the up to 86 before heat will come out in the winter. Â will sometimes correct itself if car is turned off and let sit for a period of time.

After owning the car for a year the passenger's side heat doesn't work at all. We took it in to get it diagnosed. They told us it was the blend door and they estimated $500 plus. The mechanic said this wasn't the first time he'd seen this, that's how he was so easily able to diagnose it as a blend door problem.
2004 Jeep Grand Cherokee dual zone passenger side heat did not work at the onset of cold weather. Dealer stated the blend air door was broke. However to fix the broken part the entire dash assembly along with heater coil and ac coil had to be removed. The cost of the part was minimal compared to the labor expense to replace the part.

The contact owns a 2004 Jeep Grand Cherokee. The contact stated that she is experiencing failure with her vehicle's power windows. She stated that her power windows fail to roll up.

Windshield visibility frequently reduced due to failure of heater/cooling system, vehicle has no heat for defroster (or occupants). I took the car to the dealer, described the problem and was immediately told this was a known problem in the Jeep line with the blend door mechanism and would cost $1,200 to repair. Note: this was based solely on a description, no mechanic was required to look at the car; this issue is that well known to the dealership. Further, a diagnostic would require removal of the dash, costing $200-500 just to check/confirm. I reported the problem at 29,500 miles (of a 30,000 warranty) but was told I was beyond the warranty date. No corrective action or accomodation was offered.
Passenger side heat quit working. This is a dual climate control vehicle. Passenger side only blows cold air.
When turn heat on cold air will come out. You will have to turn the head on and off so you can get heat to work. You should not have to do this to a 30. 000 $ car!!!! this need to be fixed. . . . This has happened a lots!!!!.
No heat comng from vents on passenger side first and now driver side.
