Blend door malfunction.

- Altoona, PA, USA

I have 2 Jeep Grand Cherokee both have had to have dash completely pulled and blend doors replaced at a cost of $1100 and they both have only 50,000 miles. I was on a long trip threw the Colorado mountains and passenger side would blow only cold air, unable to clear windshields of fog. Visibility/safety hazard. Jeep knows they have this problem happens to all of there vehicles 99-04. They even have a tsb, but $1100 to fix?

Visibility: Defroster/defogger system:windshield:blower does your dashboard have a loud creaking sound coming from its underside when you turn on your ventilation" is there creaking from the dash seconds after shutting the engine off? are there strange numbers popping-up on your climate control display? does cold air blow from one side of the dash even when you have the heat turned on" your ventilation system may have failed, or, may be in the process of failing. All of the above questions have "yes" answers to them. This is a major safety hazard because without a ventilation system working (especially in the winter), the defroster does not work. In the event of cold weather, the driver is not able to defrost his window. This problem is too common in Jeep for there not to be a recall!

Blend door failure. No heat on driver's side living in a very cold climate. $800-$1500 to fix for a vehicle that is only 3 years old. It should be a recall because of the fact it is a common problem with these Jeep.

2004 Jeep Grand Cherokee overland: Heat and A/C blower are in operative. Mid case and blend door are defective.

- Carmel, NY, USA

04 Grand Cherokee, funny noises after car shuts off coming from dash for as long as I can remember. The just last week the right side vents started blowing only cold air. I just found out it is a $1500/2 day repair and that it happens "a lot" - so to me if this is a failure they know about for several years then I should not have to fix this myself. It is obviously a lemon part and it should be recalled.

I have clod air blasting from the passenger side, even when the heat is on, and noises coming from the under side of the dash. The dealer told me it was the blend or door as soon as a I called and they even knew what it would cost to fix it. I asked if this was common since he seemed to know immediately they told me know, but when I went to the dealer to get fixed I overheard a conversation of another Jeep owner with the same problem, I paid over $1200 to get this fixed.

I own a 2004 Jeep Grand Cherokee limited with 66,000 miles. In August 2006, the ac quit functioning when air temperatures exceeded 85F. After a recalibrating, everything seemed fine. But when the temperature dropped the passenger heat failed while the drivers side continued to function. The dealership replaced the "blend air assembly" per the tsb - at my expense. Didn't fix the problem so they recalibrated the system again. Worked for about 1 month. Then no heat on the driver side while passenger side has heat from the top vent but not the lower. The right side blend doors have been replaced twice & system recalibrated 4 times- again at my expense. Still no heat on drivers side or lower passenger side. Keeping the windshield is problematic in poor weather conditions. Service manager says he isn't getting any help from daimler Chrysler. As temperatures have been below zero this is a serious safety hazard.
