Tried to attach two pics of my 92 ready for the evaporator to come out. I'm a little concerned because the old one looks fine. An A/C tech checked it for me with a sniffer, and the only place it alarmed was at the bottm of the evaporator, so I hope this does it?

Joe, any pics of the evaporator??
It took me about 4 hours to get to the point in the earlier pics--just ready to remove the heater/evap unit. It then took me about an hour to pull remove, swap out the evap, and re-install. Then about 4 hours to reassemble--I finished last night--will get it charged on Monday with R134 and hope all is well. Chris, here is a pic of the old evap--not much to see....I also added a pic of the new evap in the heater/evap box ready to install.

Joe, are you sure the old evap is only 2 years old ? My original evap looked newer 
Any evidence of oil on the evaporator?

Chris,
Actually 3 years old, and you may be on to something. Maybe I've had 5 evaps fail because I work at a chemical plant? Acid in the air eating the thin aluminum? Anyway, I found maybe less than one ounce of oil on the bottom surface of one of the pipes--it was clear, and I only noticed it from touching it. It probably is bad--only place that showed freon with the tester--will know more on Monday--also my A/C tech friend says he can and will test the old one.
Thanks again for all your help--I honestly would not have tried this myself had you not had success with yours and posted here on Prime!!

If there is oil on the exterior of the evap , Im sure it must have been leaking. Sounds like you did an excellent job and I'm glad I was a help to you. :wink:
Were you nervous about doing the job(pulling dash) yourself??
Absolutely I was nervous. I think the dealer charges 10 hours? When I saw the pics from Zennsx (Chris), I was even more nervous, but he told me the pics made it look harder than it is, and now that I did it, I agree. The manual was a big help too.
I imagine it was rather rewarding too.
I have done a few task myself involving pulling out panels, wires and as such and putting them back together and it is fixed. Nothing to that extent yet though. Congrats on doing it yourself !!

so is most of the hours quoted for evaporator replacement mainly taking the dash apart? if you have a crap load of time then the difficulty is not that bad? if it was either DIY or $4k to fix the GD A/C i think i'd do it myself even if it mean doing it underwater :biggrin:
I'm not sure how many of the hours quoted are for taking out the dash, but that is a big part of the job. Getting out the dash requires taking out the seats, everything in the center console, drop the steering, the gages, etc, which takes time--none of it is too difficult. I was quoted $1936 for the job before I did it myself--if it were to cost $4K it would be an even easier decision.
