Customer Question

Working on AC on a 2002 suburban. Can't find leak, I have leak dye in the system and have removed and replaced every component except the condenser I have it loose and can see both the front and the back no sign of oil or leaks. Bolted new compressor in
place and pulls a little higher vacuum but still leaks off in less than 10 minutes.

Did you replace the evaporator?
Customer: replied 1 year ago.
No, but I have removed and inspected both the front and rear evaporator. replaced all of the seals and the orifice tube yesterday i pressure tested the system and found a front compressor seal leak. but I may still have another small leak still checking. this has been the hardest ac leak that I have ever tried to find.
