Hi. The air suspension compressor is common to fail. But first what you should check are the height sensors. There is one on the left front and right front. And one for the rear. Sometimes the sensors pop off the ball stud and then it disables the air compressor. Check that first. If those are ok you will want to try and manually turn on the compressor to make sure it works.
I believe the right hand side. Attached to the control arm. I will see if I can look up a diagram for you.
There is not one for the rear. I worked on an 06 navigator today and it had a rear. Your year does not. Just the two in the front.
Yes. Still check the front 2 sensors.
The next step would be to either have the air suspension module checked for codes, or apply power and ground to the air compressor to make sure it runs.
ok. you are welcome. let me know if you need more information.
In the fuse box under the hood there is a compressor relay. Make sure the relay has power going to 2 of the terminals with the key on. The owners manual should show the location of the relay.
That is possible. Usually a ride height sensor becomes disconnected. To test if it is actually not working you do need a scan tool that can monitor it to make sure it is reading. If you have power at the relay location in terminal 3, you can jump power from terminal 3 to 5 and see if the compressor will run.
All power should be checked with the key ON. Fuse 19 (60amp) in fuse box under hood, sends power to terminal 3 of the relay. Terminal 1 of the relay gets power from the Vehicle Dynamics Module. Fuse 53 (10amp) and fuse 48 (30amp) in the fuse box under the hood control the VDM. If you do not have power on those terminals of the relay, that will have to be figured out first.
