Air suspension light has came on and went off over last few months. I had a flat tire on R. rear I didn't turn off air suspension. now the rear of the car will not rise. I can hear compressor under hood come on. what should I check?
Also have a shop check to see if one of the rear air bags is over-extended and leaking.
Check the air lines for leaks especially around the right rear tire area. chances are the flat tire severed or pulled loose one of the lines from compressor

I have serviced these in the past and it will probably be a combination of things. I just a few weeks ago fixed a 1999 with the same problems. Generally from past repairs, the electric pump has been working overtime to compensate for leaking rear air shocks. The best solution is to replace them both, not a cheap repair, the pump around 275.00 and each shock arount 275.00.
Just with every thing over time things fail, the rear shocks develop leaks over time/weather cracks, they are easy to check, soapy water will identify this as the problem. If you can get under it enough to spray around the bottom of the shocks when they are inflated. These systems are computer controlled and if you have the proper scanner you can check the system out for eletrical problems easily. My past experiences with these suspensions as almost always the shocks and pump.

probably a leak in the system. check the switch in the trunk, make sure it is on.

Sounds like the compressor isnt getting power nor told to do so.
My first step to try for power is to go to the engine bay, Go to the fuse box above the engine and swap the Horn relay for the one in air suspension and try using the horn. If the horn doesnt work theres your problem!
Next step if above fails. Is to check for any blown fuses and replace as needed then retry.
The air suspension also has a height sensor on it, If that has failed the car wouldnt work out where it was and wouldnt adjust. also there is a Air Suspension/Evo Steering Module which controls the system but if there was a problem with this i belive you would also loose power steering.

Those Lincolns are notorious for that,I'd just get a set of coil springs out of a Crown Victoria cop car(junk yard)and swap them out.Done it many times,you can do it in about an hour,and they'll never leak down again.By the way,there's some O-rings in that system.Make some soapy water and spray every connection,just maybe you'll get lucky.
