AC evap
 

Where to find help to change out the evaporator , 93 XJ

Help as in how to DIY yourself or what shop/shade tree mechanic to take it to and have them do it?

If the former, there are LOADS of YT vids on this. While many may focus on the heater core (change this out too), you get them both for the same effort. So go look at a bunch of them to make sure you are familiar with the process. Especially the section on reassembling the box.

But first, how do you know the evap is bad? Did you perform a leak test to verify?

Thank you I’ll check out the YouTube videos online. I recharged my AC and it was working fine for about two days then going down the road. My wife heard the psssss sound coming from the dash around the glove box, and the AC stopped cooling. I assumed the only thing that could turn loose, that we could hear while going down the road, would be the evaporator

Certainly sounds like it. Might still be worth the trouble to add some leak detection dye to verify in case it's something else that's easier to get at.
