OK, so today I spent getting my AC working again, I was hell bent to find this leak and I think I got it..... Went through and replaced every single O-Ring in the system, vacumed, and recharged the oil and refrigerent.... It held Vacume for a few hours so Im sure I got it.... NOW, this problem started before that last leak devoloped, so its been ongoing. The driver side air spits warm air and the passenger is ice cold, after about 20 min the drivers side sllllooowwwwlllyyy turns cold... I do not have the fancy dual climate or anything like that, just your basic manual knobs. Does my system still have those acctuaters that open and close the diffrent sides? and would that cause my drivers side to very slowly turn cold after 20 min?
