Your air bags are for when you crash, unless youre driving a custom lowrider. An air suspension system problem doesn't have a light, just a fault code in the computer system and will dispaly as a digital message. You'll need to take it to a shop with the proper equipment for diagnosing air bags in ordeer to have the light turned off.
The shaking is likely your half shafts and can usually be identified simply by examining the dust boots. If they're cracked or broken dirt will get inside and the bearings being quite sensitive and under a lot of 'pressure' will grind themselves into oblivion with small amounts of debris.

I added air shocks to my 1995 lincoln town car because the air suspension bags died. what pressure should they take and do they lose air so you have to add air?


The Stock Air Bags self Leveled, your new System should have come with PAperwork or is there a Air Nozzle that you have to fill? The Bags should come with a Pressure Window for a Firmer Ride or Softer Ride.

How to reset the check engine light on a 2005 Cadillac STS V8?


If the check engine light is on, there is a problem that the computer has detected and it needs to be fixed first. Once the proper repair(s) have been made you can use a code reader that has the ability to "reset" the light. You could also just disconnect the battery for 15 minutes. If the problem hasen't been fixed the light will come back on.

My mechanic installed new shocks on the rear of my 06 SRX that did not have the air bag. I now have a message on my display screen that limits my speed to 80. Do I have to install the right shocks or is...


Why did you not install the correct shocks.Cost is high, but its a Cadillac, they dont make them with cheap parts, if they did, it would be a chevy. I dont think there is a fix.

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.

Service air bag light on. Limits the car to 90 mph


HI, First off, it's hard to say what is causing the rattling under your car (for anyone, even a tech driving your car), so the best way to find out is to have it put on a lift and checked. Many service centers that sell shocks adn struts will take a look for you, mostly because it's a potential job for them. Any shop that would charge you to do this is not the place you should be taking it to. Second, in the STS, while there are airbag sensor problems reported occasionally, the sensors are usually the ones behind the front bumper. Is it possible that the person who told you this may be talking about the "shock" (hydrolic piston) that the front bumper is attached to? The sensors are right there, and maybe they mean that a bad piston can create a problem with the airbag sensor. That sounds accurate. As far as while you're driving, the sheer forward air pressure forced against the front bumper may be setting off the faulty sensor warning. It's speculation at this point, but it just may be the problem. You can take care of these individual things in a measured way, and avoid paying for unnecessary repairs.

On a 1999 cadillac deville I replaced the front and rear brake rotors and pads. After this, the warning lights anti brake and tracking lights are on. I'm hoping that the computer needs time to adjust....


Try disconnecting the battery fo at least 60 seconds, this will manually re-set the computer. It will sometimes take a day or so for the light to go out. If it has ABS find a dead end street and get up to 40-45 MPH and slam on the brakes and check that everything is ok. That's the only way to properly check and not endanger any people. Good luck.
