LINCOLN TOWN CAR AIR SUSPENSION

1992

If you are going to DIY on your car, you should always get the factory service information. Chilton, Mitchell, Haynes, etc. fall very short. The FLM factory service CDs are available on eEbay for under $10. Like this one:

You can also get the paper service manuals for your car at but the set will run $200+. Used books are available on ebay for ~$40.

What's wrong with your air suspension? It's a pretty simple system. Tom

Yeah, I have the same issue, and i don't own a TC :)

Seriously, the problem is most likely the rear air springs. They develop cracks over time where the bottom of thr bag rolls under itself. If the bags were leaking for a while it usually overworks the compressor and it fails also. This is by far the most common scenario. The controller rarely fails, same for the spring solenoids and height sensor.

If the compressor still runs then Order 2 rear air springs from

, , or They are about $80 each. Also replace the dryer (plastic canister on the pumpwith the air lines attached) as it will be saturated from over use. It's ~$35. Don't bother with used parts, they are usually bad too.

If the compressor doesn't run, first try to air up the suspension through the schrader valve on the compressor (have the ignition on and the doors closed). If the rest of the system is working the rear bags should inflate, or you will hear leaking from the bags or lines. If you hear leaks or the rear raises, the compressor is likely toast (A bad pump relay is possible, but again, failed compressor is more likely).

If this were my car, I would bite the bullet and replace both springs, compressor , and dryer. (about $210 total) This would bring the basic system back to solid. These parts are 13 years old and have outlived their life expectancy. Then if there were still problems, the rest of the parts are fairly inexpensive and available used.
