A/c ?
 

Is there a schrader vale in the accumulator under the low pressure cycling switch? Mine seems to be kaput, A\C works fine with the switch jumped and the switch will close if you wiggle it. I don't want to change it if I have to evacuate the system, since I will have it all out in a few weeks for the LS swap. Jay

yeah thers a schrader in there you can screw the switch off and wont lose any freon cheap to replace but I have found the pigtail to be the culprit also.

Got it jumped with a wire and two spade connectors, and cant get it to quit with any number of wiggles or jerks. So the connector seems ok. Jay

I would put a switch in it. After you crack it loose you can take it off with your fingers and there is an O-ring to watch for sometimes they stay on the accumulator and sometimes they dont. Rob
