it will not stay run he said it was a crank sensor

Its controlled by a relay under the hood

the air pump has gone out. possibly because of air leaking from air springs. non stop air pump working has wore it out and may need replacing.

Sounds like you need the compressor and airlines checked out.

try turning the air ride compressor off and letting it go all the way down then turn it back on and see if it fixes it. the switch is either on the right hand kick panel or in the cargo area. if this does not fix it but the vehicle does lift up it is more than likely the level sensor causing the problem it is attached to the suspension.

The navi has leveling sensors on both axles that are switches and are adjustable. Most likely these are out of calibration. DO NOT attempt to move or adjust these with the vehicle on jack stands. Vehicle could shift and fall resulting in serious injury.

Leveling sensors froze up ? Have you been through snow & slush?
Can the vehicle be stored in heated garage for a night?

i have 2003 lin nav and the fron pass. is down i have a new compresser and relay it worked for one day them stopped. i bypass to the compresser to let the truck up then turn the switch off but the front still go down and the compresser dont come on by itself, help. i think they should have a recall on this to many people with he same problem

The FX is a bouncy car, but it's necessary to accommodate it's good performance. You can try some aftermarket air shocks, or check into different tires. That should help.
