Talking Re: Faulty ac expansion valve?
Can you confirm the compressor crankshaft is turning when the clutch is energized???

Does the engine slo with the INCREASED LOAD on the engine, proving that the compressor is taking power??

Does the fan come on to indicate that the a/c switch is correctly sending power to the compressor and fan?

The discharge line on the compressor should show heat even with a plugged orfice for a few seconds due to the heat of compression and compressor losses.

Let us know, and gauges should show a high hi and lower lo if only for a short time. Also your dryer could have moisture and be clogged, did you evacuate the system after the repair/fix.
