The defroster blows cold air randomly while driving in the winter. Causes the windshield to fog, then freeze while driving. This is a very common issue and easy fix, but requires removing the entire dashboard assembly. To replace a $5 piece of plastic. This is a common issue and a safety problem and should be covered by the dealer.
Same common problem that has occurred on thousands of Chrysler/Jeep Grand Cherokee's. The blend door actuators that regulate hot and cold air fail so that heat stops working entirely. This also means the defrost stops working which is a major safety hazard when driving in wet and cold climates like the winter months in washington state. I recently drove over one of our mountain passes and could not see anything because it was snowing and I could not defrost the windshield. The repair costs $1600 at a Chrysler dealership.
The heater on my 2002 Jeep Grand Cherokee only works approx. 25% of the time. The person I purchased it from said it only happened to her every so often, but that it had gotten worse. Since I've owned it, it has continued to get progressively worse. I'm concerned as winter is approaching and I'll need to see out the windshield and will need a heat defroster for it living here in nebraska. This is a long known problem and I'm shocked that Chrysler has not recalled this problem as it poses major safety implications. I've worked on cars for 15 years and have never heard of a heater going bad. As any mechanic out there, heaters don't go bad unless the whole heater core is bad, in which case I'd have a floor full of anti-freeze, which I do not have. My Jeep has not lost an ounce of fluid and runs at perfect operating temperature. It's an obvious electrical problem that Jeep should be held accountable for! there are numerous posts on numerous forms with hoards of people having the same problem that Jeep is charging $1500 to fix. Talk about a scam!!!.
2002 Jeep Grand Cherokee overland. Heater/defroster blowing cold air causing windshield to freeze up. I searched the complaints and cannot believe that there hasn't been a recall on this model vehicle. Has 60 minutes or the national media been apprised of the problems with this model vehicle? this is what I believe is a serious problem. Maybe not if you live in florida, but I live in connecticut. I only hope someone wakes up and addresses this issue!!!!.
The automatic blend doors to control the heat are broken and now only blows cold air out of my vents, my windshield now freezes up very easily and makes driving in freezing condition very dangerous.
Cold air blowing from passenger side vents and windshield defroster regardless of control or temp settings. Driver side temp adjustments work properly, but passenger side and windshield defroster controls do not provide any heat. Windshield does not defrost, as temp mix is not functioning for passenger vents or for windshield defroster. Problem has not been resolved.
No heat, poor defroster performance. Was told the problem is the heater blend door has failed and the cost is around $`1,800. 00 to repair. I started last winter with no head on the passenger side, now there is no heat on either side. Defrosters not properly clearing windshield.
Heater/ac blend doors have detached from the shaft attached to the electric motor. The doors circulate conditioned air to the cab and are responsible for defrosting the windshield. The windshield no longer defrosts causing visibility issues during the winter months.
I own a 2002 Jeep Grand Cherokee limited with 84,400 miles. The events leading up to the failure of the ventilation system were (1) rapid fogging of front windshield,(2) fogging of front passenger windows,(3) failure of passenger heat while still maintaining driver heat function, and (4) only cold air release on passenger side of Jeep. Consequently,(1) the windshield and front windows do not defog, and (2) no heat whatsoever comes from the passenger side floor and dashboard ventilation system. To correct this problem, a "blend air door" is necessary at a cost of approximately $1,200 inclusive of 7 hours of labor. According to the certified service department at the local Jeep dealer and online forums, this has become a very common problem for 2000-2004 Jeep Grand Cherokee limiteds with duel zone ventilation systems.
Inability to see through the windshield due to excessive moisture on windshield and unable to clear windshield.
Failure causes windshield to fog up and driver cannot see roadway. All ac and heater functions fail. This is the 5th failure after reepeated repairs. The vehicle is unsafe to drive.
