Hi, I am repairing my CC: compressor seal leaks, etc. I noticed a previous tech installed a low-pressure R-134A test fitting in the high-pressure side. I intend to replace this with the correct high-pressure fitting while it is apart; anyone know a part that will work (i.e. fittings are correct)? Car had been converted before I got it and the CC works OK but the gas won't stay in it long and it is obviously leaking out the compressor seal.
Also, sometimes when tooling along in Cool mode, it would suddenly switch to hot. Maybe the evap temp sensor? What do you think?
