A/C compressor won’t engage

[ajamesd78]

2007 Dodge Ram 6.7 Mega Cab with and A/C compressor that won’t engage. I checked the wires and they are connected at the compressor. Dash lights up when A/C button is pushed but the compressor doesn’t react.
Before following other advice online of replacing a TIPM, I just wanted to ask around if anyone had this problem and solved it. The A/C was worked on last September when the condenser fan blew off the firewall. After replacing the can and lines, the mechanic vacuumed and replaced oil along with orfice tube. I specifically requested that. I checked fuse but not sure what relay to check. The power seat still works and fuse is good. Thanks for any advice.

Have the system checked, it may be under charged or you have a leak, in which case the compressor will not kick on, one way to check it is put it on defrost it should kick on the compressor.

Been using defrost pretty regularly the last 2 weeks with the Florida moisture. I’ll have it checked for system pressure.

I would start by checking fuse. My Charger did that and turned out to be just the clutch fuse.

Knowing it had work done recently I'd take it back to the shop and let them check the pressures. Chances are it has a leak.

Cutting and pasting direction out of a manual is all well and fine, but does no good for the average owner who has no clue how to run these tests.
