I am a GM tech at the dealer and if you are unfamiliar with the car and the common problems they have even a trained eye can have a hard time. The guys at the dealer see the same crap every day and usually know what it is before they even pop the hood because the same stuff usually breaks on each type of car.

I was not trying to be a dick and I said in my first post that I have seen many evaporators on these trucks and Mopar in general. When you talk on these forums it is hard because you do not know any persons actual background. The AC system is one of the easiest to diagnose I was just giving my two cents. I have worked in independent and dealerships and have seen much higher technical aptitude in the dealerships than an independent. I was just trying to help you find the problem without guessing.

I am, screw OEM in this case.

Sucks ***, this is going to be some work. . . .

Really crappy since it's such a new vehicle too.

How would you test the new one before installing it in?

I always charge the new vessel with nitrogen then bubble check under water. You could cap the ends and use compressed air too. Just be careful if you don't do this kind of work. You are probably safe using a good aftermarket brand without testing BUT look it over closely, its alot of work to do over again.

It will likely be fine when you first install it. There is no way to know if will fail after a little or a lot of time though.

Not much else I can do. . . . I'm thinking I will assemble the AC box and pull a vacuum, let it sit for a while and see if it holds.

Well a vacuum can find some leaks the evap is under pressure ALL the time. So you would idealy want to test it around 75 psi CAREFULLY.

Just assemble all the ac stuff before you put it all back together and run it and you can then use your sniffer to see if you pick up anything

The sniffer seems not to be as accurate as I want. I found the die first.

So what else should I do with the system?

So far, I want to replace the evap and the drier. The compressor seems to be okay, no other spots at all with the die anywhere.

Should I leave the die in the system? If not, yet again. How/should can I flush it out?

I think the orifice tube is okay to leave alone since the compressor did not come apart as I first thought.
