Last week I bought the 2004 SLT 4x4 Sport Durango. Had 50 miles or so (Brand New) I brought it back to the dealer 3 days later as the a/c blew hot when sitting in traffic, going at a slow speed, or idling. The temperature guage seems to also rise slightly above midline towards the hot. Dealer took 2 hours to tell me at first, they "think" it may be a gas saving feature, when the outside temp rises above 100, and that a switch needs to be flipped to turn this feature off. Then I was told by the manager"They needed to reprogram the computer". Then, they finally handed my vehicle back to me and stated"It was short 1/4 on freon, and they put dye- to check for leaks, which there were none." So, I took it home. It was fine for a day, and now it is back blowing hot air at these various times. I am about to call the dealer once again, and have them keep it until they fix it!. I live in Tucson, and last week was over 110 degrees every day, I am not happy. Anyone that has any input I may relay to dealership/service center would be great. They need to fix it now. What I don't want to happen is to keep bringing it in with another bogus answer. HELP

 

read some of the past posts on this topic. this is common, and one lister seems to have the problem and fix figured out.

 

i thought i had this one fixed.mine was a pound over on freon. it worked fine till today. i had the same problems as you did.once the gage went over half the ac would shut off.today it didnt go off till i reved the moter till 2000 to bring the temp down while idleing the damn thing went off again and i had to turn off and re start to get it to go on. keep us informed on what fixes yours.
