Default Can't find a/c leak!!!

so about a week ago, i had multiple o ring seals replaced. I also had it recharged twice, and the WHOLE a/c tube assembly replaced...$400 dollars of work. He recharged it. I brought it back two days later because it wasn't blowing cool, the a/c specialist replaced 2 more o rings that could have been leaking for free. He said he couldn't find the anymore leaks, well now it seems the a/c has gone out again. Could this be a sign of the dreaded evaporator? HELP HELP Utah is too hot in the summer!

Either evap or condenser failing... Why not get multiple opinions and bring it to another shop?

Have them use a dye in it to check where the leak is.

Dye has been in the system since the get go. The a/c tube system did blow a bunch of leaks. I'm the one who witnessed that. It blew and a bunch of dye spilled on the passenger side of the engine compartment.

I'm not an a/c system expert so I'm not sure of most of the parts and part names. So forgive me haha

Probably going to bring it to another shop today, they suggested last time have the person who did it first check it out, because of warranties

Sounds like you're just going to have to pull the dash and check all the components then unfortunately.

You can pressure test the condenser and evaporator

This is true, but judging by the OP's description of seeing the leak from the area of these components, they're going to have to pull the dash to get to either one, irregardless of which one may be faulty.

I have the same problem in my 97 Grand Cherokee. Won't last 30 min after recharge. Either pull the dash or sweat.
