2001 Dodge Caravan Need Help!

You can at least make sure it's nothing as simple as a blown fuse. Open the hood and run the engine and a/c. Locate and observe the compressor, which is run by the serpentine belt, in the lower corner nearest the radiator. If the pulley only free wheels and the center part doesn't engage and disengage, find the fuse in the box either in the engine compartment or under the dash and locate the a/c fuse. The compressor clutch is electromechanical. If it cycles on and off frequently, you may have low coolant, a leak, blockage or bad compressor. Obviously, the first possibility, low coolant, is the easiest to diagnose and fix, and it goes on up from there. Good luck.

Ok we checked the fuse and that seems to be fine, on the way home from work I started to paly with the a/c and I found that if I set my air on 79 degrees that cooler air comes out. NOT cold air but colder air, but when I set it back down to the realy cold setting for the a/c hot air comes out. Any idea what that could be. And thanks alot for your info i'm trying not to spend all the money I got but with 2 small kids if this dont work ijust might have to do that. By the way would you take it to the dealership or to a small auto place. What would be better?

Not sure, but I'd choose a good independent shop over the dealer for non-warranty work. Maybe the expansion valve is partly blocked, so it works OK on a lower setting, but when volume increases, it can't get through. Often a lower fan setting feels cooler, I guess because air doesn't pass over the evaporator coils as fast. Maybe if they flush and refill the system it will be OK.
