I have a 2011 5.0 FX4 that will not engage the AC clutch. I have done the following but still no change.

-System "seems" charged with no obvious signs of leaks.
-Replaced/check all AC fuses/relays
-Replaced the compressor field coil, pully, clutch and belt
-Replaced the AC clutch cycle switch

All replaced components are factory new Motorcraft

I'm at a loss and will most likely take the truck in for a diagnostic but was hoping that there may be something I missed before I do.

Any help that can be lent would be greatly appreciated. Thanks.

 

Has this been verified with a set of gauges?

 

It has not which is why I will most likely take it in as I do not have a set.

 

Have you checked the electrical plug at the compressor for power? Pressure switches will cause this. Also check dash control to make sure that switch is good.

 

Also you can get a low pressure gauge from parts store. The kit for adding freon to system. Check and see how much pressure is there with it not running. Dealer may ream you on a/c problem.
