I bought my 2004 Sedona from a dealer a year and a half ago. The dealer had just replaced the AC compressor. The day after I bought the van the AC kept shutting off. The green light would turn off and then air blew warm. When I turn the AC off and then back on the light would come back on and blow cold air. A few times I heard a loud screeching noise when the AC was on. I brought it back to the dealer, which also has a service dept. I was told that they tightened a belt that is manually tightened and it should be better now. Air stayed on and blew cold for a day or two, then back to sometimes shutting off and blowing warm. It has been this way for the following year and half. Now, it is summer again and SO HOT! I have to figure this out. Now, the AC will turn on and blow cold in the morning, still shuts itself off but I turn it off and back on again and it blows pretty cold. However, in the afternoon and for the rest of the day the AC will not get cold. I live in Florida and sitting in the heat probably makes the AC harder to get cool. I turn the AC on in the afternoon or evening and the temp is kinda cool, mostly warm. It shuts itself off more often in the afternoon and on too. The temp is not cool like it should be though. The longer I drive the cooler the AC it seems to get. I work 30 min from home, so when I am just getting home it seems to start getting cooler, but not much. The AC also shuts off more when I am not driving at a good and steady speed. When driving slower or slowing down/stopping the AC shuts off. AC also shuts off more often on any other setting than #2, or when the rear AC is also on. The engine runs loud when AC is on. The gauge for vehicle temp never runs hot and no other issues with the van. Well, windshield wipers on first setting suddenly just stops working. I turn off and back on a few times and it works again. Any thoughts on my AC problem? I have recharged the freon but still the same issues.
