I finally got my 93 Loyale A/C converted to R134a and got it working.
The last time it worked was the summer of 2006. Back then the refrigerant had leaked out and the fellow at the shop had convinced me to refill with R12 which was expensive even back then. I recall it was over $600 to refill and repair it back then when I was in Spokane visiting relatives. It all leaked out about one month later and since I was on the other side of the state in Western Washington (Spokane is Eastern Washington for all you non-Washingtonians), I didn't go after them for a faulty repair
Then yesterday in Walmart I saw a conversion kit for $44 and picked it up. No worries about properly disposing of old nasty r12 as that bridge was crossed 7 years ago (don't blame me folks, I didn't put in an undersized O-ring that leaked, call tuneTech in Spokane to complain).
The big concern was moisture that accumulated in the system. I got a vacuum pump and manifold gauge set at Harbor Freight, evacuated the system and after some fiddling with the pulser system and the A/C relay it now blows icy cold. Makes me wonder why I didn't do this years ago. I guess I had thought you needed special training or something lol.
