Pleas repair your CAPS LOCK key, it appears to be stuck on.
Check fuses F2.11, F2.14, F2.32, and the AC Clutch relay.
The fuses are in the box under the cover at the passenger side kick panel. See your owner's manual.
The relay is in the Auxiliary Relay Box #1 located under the hood on the driver's side fender.

Hello I also have a similar problem with my 06 navigator with EATC. I wanted to know if you ever resolved this issue.
When jumping the compressor directly it turns on without problem. I have checked the fuses. I have also performed a test on the relay following the direction from alldata. I took the truck to midas and they performed a pressure test and they checked the low and high pressure sensors. Everything was normal. I still have not had time to take it back to them for further diagnostics. When a/c is set to max 60 degrees i get no cold air just ambient temperature blowing through the vents. When I do select a/c I can here the vents switching and the warm air comes out of different vents. but the compressor will not engage. I have also tried doing a self test on the eatc and it just sits there cycling and no error codes come up I have to press any button to get out of the cycle. I brought the truck used and it never worked from day one. Anyone else have any insight into this. Any help would be greatly appreciated.

If you have no power to the compressor:
switch the clutch relay with another relay and check the fuses.
Jump low pressure switch see if it engages
jump high pressure switch and see if that engages the clutch
You can jump them by using a paper clip between the two wires.
With a test light see if you have a ground for the compressor. Check the wires to ensure there isnt a broken wire some place leading up to the clutch.
If you cannot find anything it will take a shop to look at the in dash unit to see if its working correctly.
