I have a 1998 lincoln navigator and my back suspension is stays down, and the front stays up. I was told that the pump could be out, a fuse or that it could be electrical problem. How can I tell? Always taken advantage of by a mechanic: Thanks, Woman

Bad height sensor or air suspension compressor has died? If you hear the pump, then it might be the sensors. If there's nothing, could be a blown fuse or the system was swtiched off (switch in the trunk)
The air suspension uses the same vent solenoid to vent front so that will be ok. The problem will either be the rear height sensor which mounts on/near left side of rear axle. Or the air suspension module itself.
I would suspect it is the rear height sensor,the link may have come unhooked or it may be sticking or just bad.
"looking 4 da relay" there is a solid state relay for the air suspension system , it is next to or near the air suspension pump located at right front of engine compartment ( relay has a 4 wire connector , colors grey/red , light blue/pink , light green/red , and a dark blue/yellow , also behide the right interior kick panel is a fuse area , 3 fuses are involved with this circuit , fuse #111 - a 50 amp fuse , fuse #27 a 5 amp fuse , and fuse #20 a 30 amp fuse , and don't forget the air suspension service on/off switch . if your not 100% happy with my answer , tell me what i can do to help .
free owners manual ?, best i can say is try ebay , here is several available on ebay.
Hi :-) I don't know how will this help, but you can check the car in the morning before you start it, look under it and check the level, is it dropped from the front or back. this way you can tell if you have a leak and where. if not then i think its the level sensor. in the 1998 you have two one in the front left. and one near the deferential in the back.
