2004 Infiniti QX56 Question: How to bypass high pressure switch?
A/C is blowing warm air and not cold at all. Power to A/C compressor clutch is ok, refrigerant is fully charged but the A/C clutch is not engaging to turn on the compressor. How can I bypass the 3 wire high pressure switch? which terminal to jump to bypass pressure switch? What is the OMH reading for A/C clutch? How can I trouble shoot A/C clutch? - infi04
Do not bypass anything, everything is working normally, except the clutch. If you are getting 12 volts to the clutch and it is NOT engaging, then the clutch is bad. It will need replacement, which may mean replacement of the entire compressor, depends on the availability of the parts. Sometimes it is available separately. - Bret Bodas
