I have had an issue with the heating and cooling unit on the dual zone control in the past, about 4,500 miles ago, and took it into the dealership to have them fix the problem. I took it into get repaired because it was not fogging or defrosting my vehicles windshield and I was unable to see during the winter when I was driving up to Colorado and had to stop every few minutes to wipe off the condensation. This was a terrifying event since it was snowing on the highway I was traveling on and there were vehicles trying to control their own vehicles which I could not see. At one point when I needed to pull the vehicle over and wipe off the condensation and unfreeze the windshield wipers from the windshield I was unable to see the railing and hit it, thankfully I was only going about 5 mph but I still banged up my bumper a little but at least I didn't die. This is an issue that is obviously due to the poor design of the vehicle since it has now gone out again in less than 5,000 miles. I cannot believe that daimler Chrysler has not recalled the parts that cause this problem and are waiting for someone to die from this design before they will do the right thing and recall. It costs more than $800 to repair the first time and I cannot afford to fix this issue just so that I can see the cars that are on the road and the lines to stay in my lane. Please help!

I have a 1999 Jeep Grand Cherokee limited. It has the self diagnostic tool build into the dual zone temperature control. I used the diagnostic tool to evaluate the problems that I was having with my heating and cooling unit of the cabin and got numerous error codes. I have approximately 81,000 miles currently. The major issue that I am having is that I cannot get my unit to blow hot or cold air into the cabin although it will turn on. I took my vehicle into the local daimler Chrysler dealership and they charged me a price for fixing this issue which at the time I thought was fair. This last dealership repair was about 3,000 miles ago. After the repair the vehicles heating and cooling unit operated properly until recently. Now the system does not operate properly anymore and will turn on but will not blow out any air at all...ever. I have contacted the dealership to find out what the issue is and they stated that they have had a lot of vehicles that have this exact issues and need to replace the original equipment again. After looking online I found a forum on jeepsunlimited.com that has about 25 pages of people with the same complaint. At this time I am in agreement that this is an issue that is related to the original design from daimler Chrysler company and needs to be either addressed as a recall or as a lawsuit from the public that has been sold these vehicles. This repair cost me over $800 last time I took it to the dealership and was not even something that could be fixed due to other errors on behalf of daimler Chrysler's original design. I am incredibly frustrated and do not know what else to do since repairs of $1,000 every 3,000 miles is out of the question and I am simply driving around with out heat, snow falling, and a pregnant wife! if something happens I will sue. The original parts are not available for review. Please contact me if there are any questions and I look forward to some type of resolution to this issue. Thank you.

Rotors are shot and it seems I'm not the only one, 4 wheel drive will not disengage even after I shift it out of 4 wheel drive (large popping noise when it does disengage). Rear wiper works sometimes and othertimes it won't. now I'm being told the transfer case is leaking and needs to be replaced (seal and shaft). At 53,000 miles these items seem ridculous. I've checked around on the internet and it seems like others have the same problems.
