Re: What about my AC high pressure cut of switch?

["David Teitelbaum" <jtrealty@xxxx>]

Minor correction to my last post, the high pressure relief in NOT on
the compressor, it is on the block with the high pressure cut-out
switch. On most cars it is near the accumulater, on some it is by the
condensor coil on the left. If your car doesn't have it maybe the shop
that did the conversion removed it. To run R-134 you have to run
higher pressures and the switch and relief valve can't handle it.
Instead of replacing with higher pressure parts they were maybe just
removed. I am guessing the discharge hose running from the compressor
outlet to the condensor coil failed from age and the high pressure of
the 134. Pressurize the system and listen for hissing from the hose.
