went to try & fix my a/c today. its fully charged. but the compressor clutch wont kick on unless i jumped the relay. Had the A/c machine hooked up to it and also noticed that my LOW side pressure is going negative ( into vacumm ) ...i just replaced the expansion valve. I sucked the A/C out for 30mins with the machine so its not that issue. what else could it be ? maybe the drier ?
