Most likely an internal short to ground in the air pump motor.
the relay for the air suspension is under the hood in the fuse box and its number 4. I just changed it on mine.
Something is wrong with the rear air shocks- either it is the shocks them selves or most of the time the air pump... But first check your fuse to the air pump. see owners manual for fuse location.
A possible cause for this is that air suspension pump is continully working due to a leaking air bag
Air ride compressor, air suspension compressor, and air pump are the names used for the same device. They are used to pump up the air suspension.
maybe because the pump whcih is located under the spare tire in the trunk or the fuse itself is not working properly. It could also be that the air suspension is gone bad.
You should check the air suspension switch, located on the passenger's side of the trunk. If the switch is off, the light will come on, also check the air suspension fuse. If both of these are OK, then the pump could possibly be going out.
I had a '94 Continental with the same issue. I left the switch on and pulled the fuse for the air pump.
The fuse for the suspension pump is not easy to get at it is in the engine compartment on the same side as the battery there is a plastic cover/box just behind the battery towards the bulkhead and you have to lift that up and the 40amp fuse is under that,if that fuse has blow then your pump is in big trouble.
sounds like your solenoids are leaking, usually in your air bag (suspension). or a hose.
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)
if you have more than 100k on it the rear bags have holes in them ,the fuse has blown cutting power to the pump that airs up the bags.
