My wife has an '06 T&C with just over 45,000 miles on it....needless to say it isnt abused!!! The air quit working about two weeks ago. It WAS as cold as a mother in laws heart....now hot air. Buddy of mine hooked his a/c guages up to the low side port, and checked it for vacuum. in 30 mins, no leaks. We rechaged it....took two of the smaller cans of 134 juice. air got cold for about 3 days..... thenl not cold. ac clutch kicks in (audible) and system draws down (lights dim ever so slightly..or flicker is better analogy)... all normal climate control functions okay. i checked the a/c blower fuse, and okay there, could it be the a/c relay? some omron relay? how do you check those? or do you just replace?

 

if U had to add freon U have a leak wont be a relay issue so dont bother looking
