If that's the case. Good chance the compressor is bad. Low refrigerant, the low side would pull into a low psi or vacuum. Clutch would cycle off. Blockage, the high side would peg and shut the compressor off. Bad compressor/not turning. Nothing happens as you have 12 ounces of static pressure and no...

Does the clutch ever cyle off? With low refrigerant, it should unless pressures stay static because the compressor is not working/turning.

You're getting away from the issue some. The compressor clutch doesn't disengage, and it's not cooling, besides the pressure reading issue. With limited information, not being there to check. If the internals of the compressor is turning. You have a defective compressor/broken shaft. The blockage w...
