Replying to: hothanddd (Jul 22, 2009 3:24 pm) I had a similar problem where the pressure showed good while recharged and running, then if the van sat for a day or two and didn't use AC, the unit would blow hot air. I eventually found the high pressure hose that is located between the radiator and the motor had a slight amount of oil on it (has some foil wrap on it). I didn't see it until I removed the plastic shroud off the underside of the engine area, crawled under it and looked up. After changing the hose and the drier assy, recharged and worked well. It's important to install a new drier and o-rings to the fittings anytime you open and replace any part of the system. Also add a little AC compressor oil when you do this.

Replying to: darkwater27 (Sep 07, 2009 8:27 am) How many miles did you have on the van at the time? Mine has done this since I bought it new in June 2006. Our Columbia, SC dealer has just gotten a new service manager and I PRAY he will get the place in shape. It is a shame to love the van but it has problems they should have been able to repair. I sometimes feel they are waiting for it to go out of warranty!!
