I just had a a/c hose replaced on my 91 carat.(leaking) I also had a new expansion valve, and dryer installed with fresh r12 Yes r12. Since then I am getting Ice cold air but the amount of condensation build up on all the ducts is making it rain in the van. One thing I noticed since the repair is I don't think the a/c temp knob is working its always Ice cold. I live in so. Florida and it is very humid down here. Anybody know why I'm getting so much condensation build up on the length of my vents in as little as a 40 min drive? thanks.Jim
