the AC stopped blowing cold air. i did not see the compressor cycle on and off. i pulled the low pressure switch and ran a jumper and the compressor started to run. i looked at each fitting for leaks. i did not find any so off to the AC shop and get a recharge. The PO did a swap to R-134A and the new valve leaked so he put some silicon in the fitting and screwed the cap back on. well it leaked. we found the low pressure switch connector was bad. we could wiggle the connector and get the compressor to run. Time to replace.
