Evaporator Core

Has anyone ever replaced their evaporator core? I understand that this is the most common problem with Jeep A/C systems. How difficult is it to replace? I'd like to save the small fortune that it would cost to have my mechanic do it.

I have found that Jeep issued new updated procedure listed in TSB 24-02-98 to replace evaporator core. However, you would have to order the details of the TSB from DC by calling 800 number or by going to their web site.

I'm no AC mechanic, but I believe the core is welded in, so you'd have to take the old one off and weld in a new one. This wouldn't be a job to learn about welding, since the ever so tiniest flaw will cause a slow leak, and you'll be doing it again....

It's my (possibly ignorant) suspicion that a pretty good percentage of cores get replaced when they've really simply started leaking at a factory weld.... Of course when you're doing all that work you may as well replace it, but to have to do it just because the weld could have been done better in the first place....

Sounds like a real pain in the A** job. Perhaps I will have my mechanic do this one.
