It's hot here so I decided to fix the A/C and get it charged after the last connecting rod came out of the side of the motor and broke the compressor off of it's mounts.


Anyway. Got it vacume then charged. And my buddy comes and tells me they could not get the compressor to come on...I was like ok maybe i forgot to put the plug back in. Nope it's on.



To make this shorter I can command the A/C clutch on with HPTuners and the A/C works fine. But it won't engage the clutch without me doing it through HPT. On the Climate controls the A/C button is depressed and the A/C light is on.


I even checked the low side or high side pressure sensor and it's plugged in also.And I know there are no cut wires or anything because if there were then I would not be able to command it on through HPT.



What could be the problem???
