Mine was leaking at the lower fitting on the condenser. I replaced the gasket and it still leaked and then stopped after a few days. Then we put the new bumper on and the AC is still blowing cold. When it doesn't, the dealer can fix it.

Do you mean passed away or just hasn't returned? If the latter, I often check the date of their last visit and hope that maybe they'll get an email alerting them to an old thread of theirs and come back and contribute. Sometimes it works.

Has anyone else had this problem with the AC leaking at evaporator and cant find it? im in the same boat with the leak problem but cant find it with the UV light. Can anyone help with experience?

Hello everyone I've been trying to look for the darn leak myself on my 2008 Yukon 6.2 Denali, I changed the pressure switch I changed the valve on the low side port, I haven't changed the valve on the high, I took it to the dealership prior , I was told the low side valve on the port is leaking and the pressure switch, I changed it and nothing. I have to put a can of freon every week. I will check the panel on the back I was not aware there was something there, I will continue to fix the issue.. I also did a vacuum test and left it over night the gauge never drop , it must be a very very slow leak...
