AIR SUSPENSION QUESTION
My right rear side is completely deflated, this happens sometimes and is usually worse when it is colder outside. I usually start it up and let it sit until it comes back up but yesterday the compressor didnt come on. Im not big on throwing parts at it without confirming they are bad. I have been looking for a wiring print just so I can confirm that I have power going to the compressor before I replace it. I disconnected the electrical connector and started the truck assuming I would have 12volts across the two pins that are connected to the 2 big wires but I got nothing. I checked the 60A, 30A, and 10A fuses as well as the relay that is above the radiator (main fuse box). It is a 2008 Expedition EL Limited. Update I replaced the compressor no help, I replaced the relay (far right most forward position I believe it is #53) No help I need help....

Don't know if it might help, but here is all the electrical parts in the Ford parts catalog for the auto-leveling system:

Just connect a meter to the connector at the compressor.Based on your symptoms I'd start looking at the right rear ride height sensor. It seems like it's telling the air ride module that all is well so the right rear doesn't get air when it needs it.

Compress no longer comes on
I had the rear airbags replaced in July 2020, the right rear leaks down daily, technician says the solenoid beside the airbag is leaking, and diag was from spraying soapy water on the solenoid with the air line disconnected. I've been debating on just going with coils but as of yesterday now the compressor will not come on to air the system at all and it's all the way down. This has been going on since July and I fear that the compressor has now burn out from over use. I need to get it inflated to get it to the technician (about 20 miles way) without it messing up anything. Any suggestions?
