2010 expedition el. I changed the rear brakes last night and forgot to turn off the air suspension. Now the air bags will not air up. The compressor is good , I bench tested that. Fuses and relays are good but it will not call for air and send power to the compressor. What do I check next?

this may help but is for a 2007. Wires should be similar. 2 sensors in the rear get 5v from ride control module and send back a signal voltage to tell the module if it needs more or less air to get proper signal voltage. Looks like 3 fuse and a relay. That operate pump and module. If module wasn't satisfied it would tell the pcm of a fault.Check your relay or the power to relay. Swap with another similar relay. Sounds like that may be the issue
