I would wonder though, if the high side pressure is high due to the expansion valve, maybe just the o rings are leaking? I'd throw that out there just to see if they might agree that the joint between the expansion valve and evap might be the only leak?

Thanks Gilly,

He said he probed it and found no leak. I looked at the FSM and it looks an easy replacement for ~$26. Since there is no gas in there right now it would be a good time just for the heck of it. Maybe I should do it then fill her up again. I've got a ton of R134a cans + oil that would be an easy fill to test before tearing everything open. Would probably be a smart decision...

Makes me wonder if it could be the same issues on my 300TE. It blows cold fine, but it really struggles at above 90F outside. I can't tell if its just the small evap the way it was designed + R134a instead of R12, or if there is an issue?

I will be doing the work myself. I just took the car in because I don't have the knowledge or leak detection machines to properly find a leak. I "tried", but failed at finding "where" it was leaking from so I just handed it off so they could find it for me.

I've also heard you can see the condition of the evap by removing the blower motor? Anybody confirm this? Maybe I can pull it off (after replacing expansion valve) put some dye in and use a UV detector and watch in there? Is there enough space to do this? Seem a good idea?

I can't wait to start tearing off everything Looks like fun...
Can't get my head around if pulling the transmission out covered in oil or doing this job...which one is worse LOL
