Passenger side warm air flow from heater stopped. Only cold air blows out. Driver side is operating fine. Evidently the air blend door has failed. This appears to be a chronic problem with this Jeep vintage. I do not understand why a recall has never been issued for this common design failure. The fix is very expensive and involves removing the whole dash. However, mopar even makes a repair kit for this issue kit #K6855685ab, that does not involve removing the dash. Jeep should be forced to recall these vehicles and correct their design flaw.

The passenger side heater does not blow hot air. It will not defrost the windshield on the passenger side and therefore causes a safety hazard by limiting sight of the driver.

My 2001 Jeep Grand Cherokee limited with 140,000 miles has had air conditioning problems where it doesn't blow out cold air, for the last 3 years. I didn't care much about it and didn't plan to fix it until I noticed that the heating system was doing the same thing. The middle vents blow out cold air and the passenger side vents blow normal hot air. I live in a state where it gets brutally cold out in the winter time and obviously this needs to be fixed for comfort and also for defrost. Come to find out that the repair is very costly $8-1800. And the most horrifying of all is that after the problem is corrected, it will only happen again and you will be forced to pay to fix it all over again because of the parts Chrysler uses. I can not afford to fix this problem over and over again. This car dealer is well aware of this problem and is ignoring all complaints and forcing consumers to pay for the problem, when it is just going to break again. This is almost criminal!

2001 Jeep Grand Cherokee blend door.

- Allentown, NJ, USA

I own a 2001 Jeep Grand Cherokee limited and though the blower motor works the dual heater/ blend doors stopped working. It was a cool night in Michigan and the windshield quickly fogged up with no luck of clearing up because of the malfunction. I immediately rolled the window down and had to drive home with my head sticking out of the window to see. Also the next morning on a sunny day the same event happened with the windows fogged and sun directly shining on me I could not even see one thing. A person could wipe the inside of the windows off with little improvement of visibility. I had to immediately pull the vehicle over for fear of hitting someone or another car discontinued driving it. This is such a dangerous failure. I discussed it with an automotive engineer and was told it is defective part in engineering by Chrysler. Because of the safety issue here should not this be recalled! even though I replied no to your 4 questions on the right the reality is a yes could be applied to 3 of the 4 if I continued to drive the Jeep Grand Cherokee without a doubt. I recognized immediately the danger of this situation to myself and others on the road and pulled over without hesitation.

I purchased a 2001 Jeep Grand Cherokee, and a few weeks later I got up in the morning and it was cold so I turned on my heater. Unfortunately I got no heat. It turns out that the blend doors on my vehicle were broken. After much research, I found out that this is one of the absolute most common problems with the vehicle. Now if it were just a comfort issue, I could learn to live with it, but the fact of the matter is that the defrosters run through the heater core. Therefore is the blend doors are broken, you have no way to clear your windshield. Since I live in Utah, this is a very important feature to have. Although this is one of the most common problems with these vehicles, there was never a recall made. Thousands of people will end up having to pay a dealership $1500 to fix their defective parts.

Blend door problem on HVAC system. Major repair.

- Arlington, VA, USA

First, when I tried to use the heat, only the passenger side would blow warm air while the driver side was cold. That lasted about a month, then no warm air at all. That was the winter of 2007. Then during the summer of 2008, my A/C stopped blowing any kind of air through the vents no matter what setting I used. The system works as far as the blower motor and cooling the air goes, it just doesn't make it out of the vents what so ever. It has been brought to my attention that this is a design flaw regarding the blend/recirculation doors in the HVAC system.
