Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hey there, thanks for the question.
First thing you need to do is perform the auto-active test of the IPDM. It will actually engage the A/C clutch to verify the circuit is working and the relay in the IPDM is good.
If the auto active test activates the magnet clutch like it's supposed to, then the problem is not likely wiring or IPDM related, it's more likely an issue with the pressure sensor or the front air control. More commonly the pressure sensor.
If you need more help just ask! if not just be sure to leave a kind rating so the site credits me for my time.
ohh one last thing! almost forgot.
If the IPDM auto active test DOES NOT work. Check the fuse for the compressor. It's fuse 42 in the IPDM.
Then your problem is likely the pressure switch. If the pressure switch is bad the clutch will never engage for safety purposes regardless if the freon levels are correct.
If you need further assistance let me know, if not just be sure to leave a kind rating so the site credits me for my time.
