Question about 1994 Cadillac Fleetwood

1 Answer

Rear air ride shock over inflate and will not deflate

The rear air shocks are fully inflated and the car rides like a truck with loud clunking coming out of the back on bumps. Last week I checked the sensor, which seemed to be working to turn the compressor on, but would not open the solenoid to let the air out when I manually rotated the arm after disconnecting it from the suspension arm. I checked the computer for codes and found nothing. After exiting the information system the computer cycled the compressor and then opened the solenoid to released the air then the suspension worked fine, for a few days. Then gradually it stated to inflate the rear shocks and now again the shocks are fully inflated and the car is clunking again. Bad solenoid? Bad control system? Also, if anyone knows, where is the compressor and solenoids, when the compressor is running it sounds like its coming from left front. Can I access them thought he engine compartment?

    I have the EXACT same problem. It started this morning on my way to work and continued on my way home. Right now the car is in the garage and the back end it up as high as it will go.

    Update and temporary fix:



    Compressor located under front left side of engine compartment behind wheel well. Its under the air box with filter. The easiest way to access is to remove plastic panel from the wheel well and trim on front left side of car (drivers side), five or six screws/bolts total. You can not just remove the trim that gives you the access you need, because plastic panel hides the one bolt that holds it on. There is also a spring at the bottom of trim holding it tight to the fender. To temporarily fix the problem you can pull the air line off compressor, located toward front of car and accessed through side hole that trim piece covers, remove the clip and pull the line. This will release the air, then replace line and clip making sure the clip is properly seated in the slots on the fitting, and put trim and panel back on. It takes a little bit of finger pressure to get the air line and the compressor fitting to properly seat before the clip with find the slots. I'm hoping when it warms up the system will start bleeding the air automatically again. I have a feeling the water has plugged the exhaust and is not letting thee system work properly.

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!!!

Range Rover l322 My front air supension is iactice/inflates then deflates whilst the back remains stable


They have problems with the air bag shocks leaking. The shocks typically have a large bladder bulit into them that will over time develop leaks causing the problem you describe. could be a damaged line to the shock but most often the shock. Start the car and run until it inflates. Stop the vehicle somewhere quiet then put your head by the top of the wheel that deflates. Listen and you should head an air leak. It usually requires replacement of the shock to fix.

Rear air shocks do not work


there can only be a couple things either the lines going to the shocks have a hole in them and air is leaking out before it can charge the shock or the shocks seals are bad and leaking out there also check the tip where you inflate maybe take the air valve out and see if thats stopping air from reaching the shock!

Why won't rear end raise up ?


I have a 2000 Lincoln Town car, had the same problem, it was the rear air suspension/shocks. They are air bags basically that levels your car and it cost about $300.00 for each at the dealer for parts and install but it also has its own motor that inflates and deflates these air bags and I also had to replace that and that cost over $400.00 installed at the dealer.

I replaced the air shocks on my Olds Silhouette with no problem and thought the problem I had (van sitting very high in back) was solved. Rode great first week or so afterwards. Now it is back to shocks...


Check the bleed port on the controller, it may be plugged with dirt. or the controller may have failed. A full funtion scanner would help find the problem.
An other option is to by-pass the auto- leveling system and install a manual scrader valve in the air line, this would allow you to add and remove air with any source. They are availble at most autopart stores.

Heard a psssssss sound from rear driver side and defleated


Hello! The rear suspension on this vehicle is air inflated. There are diaphrams that the level ride system uses to inflate rear shocks to aid in the comfort of the vehicles ride and handling. either an air line has rurtured,came off the connection at rear shock,or the diaphram itself has ruptured. Hope this information was helpful!
