Troubleshooting a 1986 Lincoln Car Air Suspension
The Lincoln brand is Fords entry in the luxury automobile market. Lincoln makes air suspension standard on their cars to deliver a smoother riding suspension than simple coil springs could deliver. Air suspension uses air bags on the suspension to cushion the frame and to regulate the leveling of the car by pumping air in and out of the bags.

Inspect the air bags on each suspension strut while the car is off. The air bags will be deflated at this point, but any large tears will be visible. The air bags must be intact in order to hold air. Also check the air line that runs from the upper part of the wheel well to the top of the air bag. If the line is disconnected, then no air can be pumped into the suspension.
2Park the 1986 Lincoln on a flat area like a parking lot or garage, but keep the car running. Put the car in Park and get out of the car. Listen caully for the pump in the engine bay to inflate the air bags. Look at the corners of the Lincoln and note if any corner is not rising at the same level as the others, or if none of the corners are rising. If one corner is failing to rise, then there may be a small tear in the airbag or the air line running to the bag. If none of the air bags are inflating, then the pump may be broken or the air tank may have a hole in it.
3Open the trunk of the Lincoln and look at the air tank. If there are any tears in the surface of the tank, then it cannot hold enough pressure to send air to the air bags. Listen for air rushing out of the tank. Inspect the air lines running from the air tank for any tears as well. Turn the car off and watch the corners as they settle down. If any one corner is falling faster than another, that could also indicate a leak in the air bag.
