Two weeks ago the evaporator core on my '86 Toyota p/u needed replacement. When I went to pick it up, I was told that they had converted the system from R12 to R134 (evacuated and then refilled the lines and used a retrofit kit) without bothering to ask me if I wanted that done.
After that the a/c was emitting only cool air, where it had previously been cold with the R12.
I returned to the shop, where they converted it back to the R12. But the air, although colder than it was with the R134, was still not as cold as it was prior to the conversion/reconversion, and now blows warm air at idle and slow speeds. (btw the drier was not replaced for either conversion.)
I again returned to the shop, where they told me this time that I needed a new condenser ( a $350 job). Could anyone tell me if the damage could have been caused by the conversion/reconversion?
Thanks :) Sue
