Spikeit Posted Friday at 02:03 AM Report Share Posted Friday at 02:03 AM I recently replaced the a/c compressor with a well known brand. I didn't disturb any wiring except to hook up the provided wiring adapter from the new compressor to my oem plug. I've gotten some freon in it but no matter what I can't get the ac clutch to engage. I've swapped relays with no luck, all fuses are good, checked wiring continuity from the relay panel to the compressor and for power TO the relay panel and all are ok. What am I missing??? The ac worked great until I swapped the compressor and only did so because the old compressor started leaking oil from the rear cover and yes the bolts were as tight as could be but the leak continued. Any thoughts/ideas anyone? TIA Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted 8 hours ago Report Share Posted 8 hours ago Most likely stems from low refrigerant pressure. Is the system presured properly? If the pressure is outside the safe range (30–40 psi on the low side and 200–225 psi on the high side), the compressor will NOT kick on. Although unlikely, couple of other possibilities include a blown fuse or malfunctioning pressure switch. Check fuse #35 in the power distribution box (in engine compartment.) My guess is you didn't pressurize the system sufficiently (you stated "put some freon in it".) Quote Link to comment Share on other sites More sharing options...
