well the compressor was working, but making a clattering sound. could this be due to not being used for a couple of years? the air was cold at first but then not so cold. the indy only put a pound of refrigerant in.
i understand what you are saying when & if the compressor fails.
btw off the topic - i was in wal-mart here this weekend and they had hundreds of cans of R-134a stacked up there , floor to ceiling!!
