AC Leak
99 xj 4.0 4x4
Well I turned on the AC a few weeks back and got warm air. So we charged the system with dyed refrigarant. Worked fine for a while but now warm air again.
The compressor is engaging.
The problem is we cant find the leak anywhere. I guess I'm going to have to bring it somewhere and have them use a sniffer.
Am I most likely looking at doing a evaporator/heater core job?

If the compressor engages and the return line gets cold enough to draw moisture out of the atmosphere (a good sweat) then I suspect you might have a blend door problem. Verify your temps first
