Auxiliary air compressor

[Dieselcar]

good morning all, my aux air compressor has stopped working. We have an 04 Monaco Dynasty with the airbag leveling system. That works fine, just the compressor isn't working. Anyone know where the fuses are located...Thank you...Ronnie

The main fuse is almost always located in the Front Run Box which is the large electrical compartment on the exterior directly under the driver's window. Typically a 15 or 20 amp fuse labeled "Aux Comp" or "Air Level". In many units it is a gold colored rectangular maxi fuse. likely on the RH side or rear wall of the electrical box.
If the fuse in the Front Run Box is good check for an inline blade fuse at the compressor in the harness. The fuse may be in a weather tight box, right next to the White Rodgers solenoid on the compressor motor itself.
Could be the pressure switch if all the fuses are good or the solenoid ( you can test if it's the solenoid by jumping 12v directly to the compressor motor side of the solenoid).
