    could be the rear height sensor.

    this is 96 Cont. Don't have 1990

    Section 04-05: Suspension, Computer Controlled

    1996 Continental Workshop Manual


    Suspension, Computer Controlled

    The air suspension system incorporates air leveling and road calibrated suspension ride control in one suspension system.

    • Air leveling maintains the vehicle at the proper level under varying conditions of vehicle load.
    • Road calibrated suspension ride control switches the shock absorbers between soft and hard damping.

    The air suspension system includes the following major components:

    • Air compressor to supply air to the air springs (part of front spring and shock and rear spring and shock absorber assemblies
    • Front spring and shock (3C098) and rear spring and shock absorber (5A965) at each corner of the vehicle
    • Four linear air suspension height sensors (5359): two rear and two front height sensors to maintain the vehicle at the proper ride height; only LH rear height sensor is used for air suspension.
    • Dual-mode front spring and shock and rear shock absorber assemblies with internal actuator.

    All system functions are controlled by vehicle dynamics control module (5A919). This control module receives inputs from several different sources. These inputs include:

    • vehicle speed via multiplex communication network
    • ignition switch position
    • door position via multiplex communication network
    • height sensor position
    • air suspension service switch
    • engine rpm via multiplex communication network
    • ride and steering personality settings via multiplex communications network

    Communications monitor system operation and allow diagnosis of any concerns that may develop in the system.

    • System monitoring for the driver's use is provided through the instrument panel mounted message center indicator (10D898).
    • Diagnosis communication for the service technician is provided through the data link connector (14489) (DLC) under the instrument panel and Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent.

    The message center indicator will display AIR LEVELING DISABLED or CHECK RIDE CONTROL if the suspension system is not turned on or the vehicle dynamics control module detects a concern. If air leveling system disabled is displayed, check that air suspension service switch is in the ON position.

Trying to find a wiring diagram for air compressor. Rear air ride is out compressor not running at all checked fuses just replaced relay .

I know that you are trying to fix that air ride, but i put these replacement springs on my 93 towncar. Fixed the compressor problem (eliminated it) and cost a whole lot less. The install is kinda hard if you've never dropped a rear end before. Need a good tool set, a couple jacks, and jack stands to get it done. Check it out. Even having a mechanic install them would be cheaper than replacing a compressor.

Where is the air ride system pump located on a 1996 lincoln town car. i also need to no how to get a diagram of it>

It is possibly located under either one of the front guards, I had a 1990 ford fairlane (Australian) and that is where the Air Ride compressor was located in that.
They usually run dry and wont pump the Air into the system, I removed the 2 rear Air Shocks from mine and replaced them with normal air shocks that you pump up at the garage and never had any more trouble.

Air Ride issues

My mom has an old Lincoln, they're great aren't they. At least that's what she thinks. :) When I had to help her fix her problem with her back end dropping I contacted Strutmasters. They made me aware of the air ride and the difference in a conversion kit for it. We purchased the product and fixed the problem. Since then I have used them for my own vehicle and suggested them to friends. Now I am suggesting them to you, they will help you out tremendously!!!! GOOD LUCK

I have a 1993 lincoln mark viii trying to manually add air to rear air bags i have installed the hose kit but they wont accept air how to fix

Don't bother. Check with srtutmasters or other alternatives. If the car was made in 93, all bags will be leaking and eventually the compressor cant keep up and fails. even your local lincoln dealer will not be able to diagnose the problems with their "computers." You can get lifetime struts and spring, in your case just springs for the rear, lincoln shocks still work. Put new struts and springs in the front. The only difference is the car will not lower itself at 60 mph or higher. the ride is the same.

My 1995 continental has severe ride problems bounces on every bump in the road front end sits low and rear seems normal

Sounds like the front "air ride suspension" is out.
That works off rubber bags built into the springs. If one or both has developed a leak/hile, it lets the front end (or rear or both) drop to ride on the bottom of the suspension.
Get the wallet out. It's expensive.
Sorry :-(

Air ride lights comes on, back end of car is low. How do i fix that?

That means there is a leak and/or malfunction on the air ride suspension system. You need to check the whole thing From the compressor all the up to the shocks. Most common problem is just the hoses that dry up, crack and leak after a few years. After all its just rubber so it's not invulnerable. But it can also be the air compressor that is not working, or the shocks themselves that are shot. In most cases, only the back end of the car has air ride, and the compressor itself is either in the trunk, or under the car in the rear end in 99% of the cases, so it should shorten the search for the system a bit.
