“My air condition and heater do not blow air into the cabin. Chrysler tells me that it is the blend doors. I was also told that this is very common with this vehicle. The estimate for repairs is $2,200. If it was something I did to the vehicle I could understand but I now have a 1999 Jeep Grand Cherokee limited with all the bells and whistles and air or heat.”
NHTSA complaint #10244575, filed 2008-10, 130,000 miles“The heater fan in my 1999 Jeep Grand Cherokee stopped working and there was a burning smell in the car. Mechanic found that the fan resistor (computer) and pigtail that connects to it were burned up. He checked with Jeep and there are 3,000 of these items back ordered because this is a problem on many of these vehicles. Its winter and 17 degrees in my car I could freeze with my family or my dashboard could catch on fire.”

Maybe water in my oil. I changed the oil this weekend when it was 2 degrees out and the white foam was frozen in chunks which then fell down the tube. Is there a TSB for this problem. I have heard similar problems from others with the 4.7 liter. How can I get this problem corrected by Jeep?”
