SOURCE: REAR AIR BAG SUSPENION

I would recommend going to strutmasters.com and taking a look at there conversion kits. these convert you from the airbag to a powder coated American made steel coil spring that is guaranteed to last the life of the car. Airbags and compressors are constantly having to be replaced. Also something alot of people don't know is that theses air suspensions are not meant to be in temperatures above 90 Degrees or below 40 Degrees. That is most of the world. The temperature will cause you to replace alot of bags. and typically when your replacing a bag you are going to have to replace the compressor to because the bag had a hole or small crack in it causing the compressor to over work and it will die. I posted the link below so you can take a look http://www.strutmasters.com/lincoln-suspension-parts-s/1.htm I hope I was of some help Good Luck!!!!

Shock sensor light will not turn off


If Original shocks are air operated, you can use rancho shocks but will have to install a diode to turn off the light. Be sure to disconnect the air compressor (located under left-rear fender between LR Tire & Rear Bumper - i'ts hidden in there.)

Air ride suspension rear dont work how can i check whats wrong?


The 97 Caddie Seville STS has an air compressor located under the car just in front of the passenger side muffler, above the crossmember. It is a pretty weak compressor, and is only designed to slowly fill up the shocks. Probable issues are a blown compressor, or leaky shocks. Before replacing either make sure you have power going to the compressor, and air going to the shocks. No power to the compressor could be caused by a bad wire, relay, connector or fuse all of which are cheaper to fix. If you have power, check the little air lines leading to the shocks from the compressor to see if you have a leak. Airlines are much cheaper than shocks.

Where is the compressor for the rear air shocks located on a 97 cadillac deville?


It is located behind the Passenger side rear tire. If jacked up and you climb under from rear bumper look to your left in between gas tank and tail exhaust. Good sized box with wire harness and clip on it.
Also if your air ride is not working in some cases the Air shock(s) may be defective the pump will not kick on

Im tryn to locate the air conpressor so I can rise the shocks.


usually this is located under the hood on fender wells. if nothing else start at the shock and follow air line to the pump. the system is on a self leveling switch located on rear axle which adjust to weight of car turning on the pump for proper ride height and comfort. you should determine why this system is not working. and yes usually there is a valve on the pump which allow you to manually introduce air into the system.

I have a 99 ford expedition i replaced the air compressor cause the front air shocks were bad and ruined the compressor. and teh rear air bags went flat now that the new compressor is in the rear wont air...


I have a 2001 Expedition, I don't have air bags in the front, the compressor don't work the air shocks. You have rear leveling. When they replaced the (compressor) did they turn the leveling switch back on. you may have air shocks connected to the compressor. Did the rear go down right after or over a couple of days. If the switch is on, turn it off and jack the rear up quiet a bit, make sure both side are quiet equal with each other, like it would be if it where raised by the air bags. Turn your level switch back on with it jacked up or sitting on stands. It may have went down so much that the compressor can't raise them back up.

97 catera leveling light flashes all the time


The problem is a leaking air shock(s). My 1997 catera had this problem also. I drove the rear wheels up on a set of ramps and went underneath. There is a sensor located close to the rear axle's that moves up when the car is loaded in the rear. (luggage/person in the back seat). When the car senses the extra weight, a small compressor located up under the hood pumps air to the air shocks until the car is back level again. With the key turned on, and the engine off, You can actually move this sensor with your hand and after about 45 seconds, you will hear the small electric compressor come on and see the rear of the car rise. Even if the shock is leaking, the car will still rise but you can hear/feel the air leak on the rubber boot of the shock. The reason the light never stops flashing is because of the air leak the car never really reaches proper leveling. I know what your thinking, "I didn't have extra weight in the car"..doesn't matter car still levels itself from time to time without extra load in the rear. Possible road conditions etc. and also the fact your basically riding around with only one rear shock working like it should. hope this helps......dave

Air ride not working


Is there power at the compressor? If not, check the level switch located at the rear of the vehicle (connects the rear axle to the body via a small arm that moves with body up/down motion)

2004 yukon xl denali self-leveling rear air shocks


There's a lever that connects the driver-side rear shock to the Automatic Level Control module (the air compressor and the ride-height sensor). Disconnect the lever from the shock and rotate it up and hold it. The compressor should kick in when you hold in place after a few seconds. If it doesn't kick in, make sure your fuses and relays are good. Otherwise, you may have a failed ALC module/burned out air compressor (from the shocks being shot). After you replace the shocks (and after you recouped from the heart attack you had when you shelled out $500+ for each shock), replace the ALC module/compressor (it's all one unit), and test it - it should kick on when you rotate the lever up again.

Figure about $350 for the ALC module from your dealer, and make sure the part numbers match! Your truck came with an upgraded ALC module from the 2001-2004 module, which were prone to water damage.

Good luck!
