Ok thats good info, thanks. It looks like this won't be a quick fix. The vehicle has two rear ride height sensors, one on each side, these supply a voltage back to the VDM module with the vehicles actual ride height. Since the compressor turns on we know the module recognizes the rear of the vehicle low. Commonly what happens is the air compressor fails but still runs, the output from the compressor will have very little air volume and pressure. When the compressor is at this stage it is to weak to pump up the rear springs. This is the most common failure we see at the dealership. There are other possibiltys and to be sure the Ford IDS scan tool will need to be plugged in to the vehicle. Since the air suspension light is on there will be codes stored in the VDM module related to the failure in the system. (similar to a check engine light). If you plan on bringing the vehicle to the dealership you can drive it, most everyone does I've never seen additional damage done by driving it in for service. Note the ride will be very rough.If you need further assistance or have another please reply and I would be glad to help. Thanks
