It's on the driver's side inner fender area, just forward of the strut tower. Look near [below] the windshield washer reservoir and the emissions vapor canister. FYI, the motor probably wore out because you neglected to repair your air struts in a timely manner. Leaking air struts or air bags cause the compressor to run excessively, which wears it out. Don't bother with a used [junk yard] unit. It will be worn out too. Rebuilding is not practical. New replacement units can be found on EBay. I'm a professional mechanic. I get my air suspension parts from Suncore Industries. Good folks with good prices. See

The air compressor on mine was under the hood on the driver's side, in front of the master cylinder

SOURCE: Rear air ride shock over inflate and will not deflate

I would recommend going to strutmasters.com and taking a look at the 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!!!

SOURCE: 99 Deville rear air shocks not working.

This is an expensive repair sometimes and you may want to replace this system with inflatable air bags that fit inside the rear coil springs and then are inflated. I think they cost about $80.00 or $120.00 depending on the car.

Need to locate the air pump that supplies the rear shocks.


The pump is back under the rear of car, but by now, the shocks are sure to be leaking, which causes the pump to run too much burning it up. Best fix is to replace rear shocks with coils and dump the self leveling feature, or prepare to pay big bucks to replace most components.

Can't find the relay switch location for air ride rear suspension for my 1993 buick riviera?


Did you check the fuse? Not only check the fuse, check voltage on fuse circuit , goes hot with key on. The bottom info should be for relay center location.

Is it better and cheaper to replace rear air suspension to non-air suspension on a 1997 Cadillac DeVille?


It will run about the same, there is a good web site we deal with that sells conversion kits or the air components needed to repair your car, we use them all the time. There pricing is good and also have all parts needed.
Your car may just need air bags, but have run into many cars that the air bags had been leaking for a while and were left not repaired causing the air compressor to run so much that it overheated and cooked the compressor and relay.This is hard to say on yours without looking at it. if the air shocks air leaking then you will need to start with that and then if the car does not lift then you will need to check the fuse and relay, if there are good or replaced and still no air is made then compressor will need replacing.
http://www.arnottindustries.com/part_CADILLAC_Air_Suspension_Parts_yid6_pid35.htmlthe compressor is 175.00 and the two shocks are 275.00.
I did not see a conversion kit for this car. take a look at site and see if you can locate one. good day.

I have a 1990 Cadillac Deville with the 4.5. I was curious if that car came with air suspension stock. I noticed a little compressor like thing right be hind the battery turn on when I was jacking it up....


The compressor will turn on when the rear air shocks are low. These shocks will begin to leak with age, and if new, can be damaged if you raise the rear end without disconnecting the battery. The shocks will fill with too much air and create a leak. If your motor runs continuously, you may need to replace the shocks. May also have a leak in the air hose going to the compressor. Check the fitting. Short fix would be to disconnect the power going to the compressor, but your ride will suffer.

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.

What would cause the rear end of my 1996 cadillac deville to drift back and forth


Something is broken or badly worn. There's a lot of potential causes so you'll need to get someone to look and make a proper diagnosis, but most commonly it will be due to worn or perished suspension bushings. If so, the suspension will need to be dismantled in order to fit new ones.

It can also be due to corrosion where the suspension mounts to the bodyshell or to the chassis, but this is all useless conjecture until you get someone to take a look ASAP. The fault won't fix itself, and will only get more expensive as it over-stresses other parts like springs, dampers, wheel bearings, tyres and it can result in unsafe handling and braking instability.

My 1999 cadillac deville air suspension not working


Check in this order: Is the compressor starting when you turn the car on? If not: is the fuse burnt, broken wires? If not: Is the linkage that connects the frame to the left rear shock broken or seized? (more wires to check here). If the compressor runs and the linkage is functional, spray some windex (or soapy solution) on the rubbers of the rear shocks and around the hoses to see if air is bubbling out. If so, this is where the problem is. Many aftermarket shocks/struts are available (check ebay) online for as little as $ 150.00 each, and $ 175.00 for the compressor.

My rear air sespension has gone bad on my 1998 navigator and I can not afford a new air sespension since they quoted me over $1900 to fix. Can I just put regular shocks on the rear to fix the horrible sag?


Yes you can, But even better yet would be a set of air shocks on there. I had a 92 Grand Marquis that blew out the rear suspension, and I put reg shocks on there, worked great, looked normal, No problem. They wanted $2,000 to fix mine. I said later. But the air shocks, if you have a full load or a sagging problem, you can just get out the compressor and blow them up. Hope this helps.
