Question about 1995 Lincoln Mark VIII
The rest of the air ride system seems to be working fine, if the front gets too low, from sitting, the compressor raises the front but wont level the rear, its still too high, Im concerned the air springs will burst if I dont fix this, all air springs are new, the car was driving perfectly till my wife drove it down a very muddy road. the next day, the rear would rise too high then the "Check Air Ride" lights up on the dash. what do I need to replace or adjust now? the compressor, the filter is new and all the air solenoids are new. I really do not want to rip it all out for a boring standard struts, shocks and springs suspension, Ideas?
This is a very common problem with the Mark VIII. The problem is excessive moisture in the system, which has found it's way to the vent solenoid of the compressor. WHY MOISTURE IS BAD ON AIR SUSPENSION
Now, the metal piston in the vent solenoid has rusted & corroded and can't more, so there's no where for the air to get out. Short term would be to replace the compressor/dryer, but long term would be to do this....but also replace 2-3 dryers in 6 months time. This way, it'll soak-up the moisture that has been accumulated.
The best alternative is to do a Lincoln Mark VIII Air Suspension Conversions

There should be a level switch in the rear of the car.The connector may have come unplugged,or filled with water.or maybe the switcch is bad.Or,it could be as simple as a disonnected or broken link arm at the switch.

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.

Save your self the hassle and expence of troubleshooting and replacement parts, install a suspension retrofit kit which changes the rear bags to coil springs and the front to struts. A car this old you might as well start over for less than $500.00......

The air pump is located in front of the radiator reservoir on the passenger's side - with the power steering
reservoir between the two.
The air ride is turned on in the truck. The panel in located on the opposite side from the gas tank input (inside the trunk) behind a door. It should be marked on the door.
Make sure the air ride is enabled. turn the ignition key on, You don't need to start the vehicle. After about 5 seconds the air compressor should engage. You don't always hear it when it's running well. Since the engine is off, you should be able to hear any leaks in the air system.
Hole/crack is air spring
Hole or broken air line or coupling
Failed air compressor
The rear suspension should use the same air system. If the pump is 'out' then the rear will also fail to adjust, But since it is on a separate air-line and valve system, it will continue to operate when the front has air leaks. And vise versa.
Two suspension systems - Front/Rear
Four air springs - One for each wheel
Another possible problem:
Your front wheels have a censor to indicate the height of the vehicle from the ground (basically). If this come unclipped, your system will think It's too high and will not add air to bring it to normal height. This usually happens on ONE side causing the vehicle to 'lean' or seem to. One side will have the wheel up in the wheel well, and the other will be a bit more gap between the wheel and the wheel well, but may seem to be 'low' too. On the side which is lowest, turn the wheel that direction and look on the front of the suspension arm for the sensor. it should be attached top and bottom.
If the clips have failed, there are no replacements available from the dealer, and replacement of the sensor is required.

It could be a wheel speed sensor that went out or something... When working with the wiring, something could have just gotten crossed or tapped to get these codes as well. The compressor shouldnt be running anymore if everything was tied off properly. Take it in somewhere and have the codes cleared and that should fix the problem hopefully. I know AutoZone has a reader, but I do not know if they have they ability to clear the codes.
I hope this helps.
