What is the best method to find AC leak? I used to vacuum and fill maybe once or twice a year and now it doesn't even last a few days. Holds ~32hg for 30 min. I cannot see pag oil residue anywhere nor in the evap drain line in the firewall. I looked at the evap through the blower motor hole when I changed it out this past winter and damn near looked brand new to me.
Dryer, O rings, orifice tube and condenser about a year old. I even went back and tightened all the fittings again, no change. This south louisiana heat is a killer.
I suspect its the evap but have no proof. My dash would not survive if I tried to replace the evap without knowing for sure that is the culprit, then I would have to buy a new dash.
any input appreciated to narrow down the leak.
