Air Conditioning problem
2003 Toyota Corolla 4 cyl Front Wheel Drive Automatic 75000 miles
A/C compressor works and cools when jumped, but won't engage when asked. Freon good, fan and idle runs up when asked, no compressor. Pressure switch? Is fitting protected- schrader valve? Any advise appreciated.
it sound as if the pressure switch has cut in, so I would go get the system pressures tested as this will give your tech a good idea as to what is going on.

Hi- thanks for your fast reply- my tech ( without much toyota experience) checked charge while the compressor was jumped to engage. It was cooling well and the freon was charged. It will raise idle and react to A/C button, but won't engage A/C clutch. No fuses appear blown.

He will need to check that the pressure switch has not activated, bridge out the switch and see if that turns on the system, if so a pressure or switch problem, if not a power supply issue to the compressor, check this next.
