2000 Ford expedition air suspension
my rear suspension is almost all the way down and the pump will not come on to inflate the suspension. I have tried to replacing the pump to no avail. Any suggestions?
There is a complex control system for the for the air suspension. Because of the complexity, diagnostics are beyond the scope of our manual. The best source of information would be a factory service manual. Online forums for Expedition enthusiasts are another valuable source of information. There may some helpful hints on where to pinpoint certain failures or common failures may be highlighted.
