Well, low and behold I went to use my A/C this week and it didn't work, even after I carfully cycled it a few times this past winter to keep things fresh. The system refrigerant level was low, and I recharged it to the proper level, and it worked for about an hour, and died again. Took it to an A/C shop in town, and the system was fully tested, and it was found to be a blown compressor. This is the first truck I have had with the Sanden rotary type compressor, and the A/C has only been used two summers. I bought a new compressor ($200) and a new dryer ($22). Of course one of the fitting nuts on the comp had to be siezed, which damaged it, and the line had to be replaced too. ($95). Question- am I going to have to go through this every two years with these Sanden compressors? The reciprocating comp on my old FL70 lasted the life of the truck and was still working when I traded it. Just wondering if these rotary jobs suck or I just had a bum one- I hope it's the latter, because this stuff was sure expensive, and I did the labor myself, if I didn't I'd be into well over $500 for some A/C.
