QuestionHi Kevin, I have a caravan and the ac doesn't hold a charge, its gotten to point of 1day. I put dye in the system charged it ran it and the only place I see a leak is coming from the drain hole, on the firewall. Could it be the core?? seals at the core? Should I pull it, what kinda a job is it? Where can I get a break down of the job also, shold I go to that Mitchell 1 for the schematic. Any help would be great. Any where else it could be leaking? Thank-you Gary
