My air conditioning nightmare.2000 Grand caravan

No cash for clunkers.Van is good otherwise.I just think my mechanic is chasng the problem by throwing parts at it..

Brian c I am in Trail B.C. So far I have replaced the rear evap,compressor reciever dryer and the small ac line to the rear evap.I think what I'll do is pick up oe of those recharge kits that comes with a guage,check the system and let you guys know whats in there.

This mech is feeding off me. Im going to make sure he is being honest.
