I recently converted my 92 325i to R134 A/C and 5 days later the compressor siezed... Initially I thought it was because I didnt put oil in the charge but I later looked at the kit and it was pre-oiled. Any ideas on why this stupid thing siezed? Is there a pressure switch that might need to be replaced on the low side of the A/C? Help!! Thanks in advance.
