Cant get air ride system to work. already replaced air pump and leveling switch. have power to both. on a 1995 cadillac deville.

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.

EACH MANUFACTURER has their Own Particular limits and ranges...

ALL YOU NEED NEW AIR SHOCKS. THAT WHY CAR IS BOUNCING.IF YOUR AIR RIDE CONTROL LIGHT ON YOU HAVE PROBLEM IN THE ROAD SENSING SUSPENSION CONTROL OR THE AIR COMPRESSOR NOT WORKING. YOU PAID THEM TO FIX CAR IF THEY CANT. GET MONEY BACK TAKE CAR TO DEALERSHIP. VECHICLES LIKE CADILLACS MERCEDES BMW JAGUAR VOLKSWAGON AND VOLVO THESE ARE SPECIAL CARS NOT EVERY BODY CAR SERVICE OR WORK ON THEM. THEY ARE EXPENSIVE HAVE HI TECH PCM ELECTRONIC CONTROL SYSTEMS ON BOARD.

these things always spring leaks.trace the tubing and you'll find it

The Cadillac's have an automatic leveling system using a small compressor and air adjustable "shocks" to provide that BEAUTIFUL ride quality that they are known for. The computer has detected a fault in the system and is letting you know. It could be a faulty air line, bad shock, or a blown fuse. I hope this will give you a starting point if you are considering a repair.

There's a level sensor in the back of most cars that have air ride suspension such as Cadillac Devilles.

If there is plenty of pressure, it's probably not a leaky air shock aborber nor is it a bad air pump under the hood.

the first thing is the fuses. i've seen many of these that the rear air shocks are bad but customer doesnt know and the pump runs until it burns out,after checking the fuses start the car and listen under the hood for the pump to turn on, if pump turns on then check shocks for leaks, also you would have to make sure the pump is producing air as it runs and the last thing is the level sensor located under the rear of car.

To begin with, check the "ride level" fuse and make sure that the ride level compressor does work, and you should be able to hear that the ride level compressor is working when the ride level system is leveling the vehicle.

The ride level system uses an air compressor and either an air type of shocks or a type of air billow to raise and lower the vehicle, there is an adjustment to set the ride height and it is located under the vehicle and there is a control lever or rod that should be connected between the rear axle and a switch that is mounted on the body of the vehicle, and there will be an adjustment slot in the control lever between the switch and the body, and that is how you would adjust the ride level height, but be sure that the vehicle can not drop any further down if someone is under the vehicle trying to adjust the ride height.

However, you might find that the control lever to the ride level has fallen off from the switch on the body or it has come loose from the rear axle, and it is just hanging there not operating the switch on the body that controls the the ride level compressor, or there might be a blown out air shock or billow, or you might find that an air line from the compressor is leaking and the ride level compressor will just run continuously until it blows out the fuse, and if that is the case you might also find out that the air compressor has burned out from running continuously.

I hope that this information will help you to solve your ride level problem.

the leveling system does have an air pump - should be behind back tire under trunk on right side - the pump works from a leveling switch on the rear suspension

Yes. There is actually a GM TSB for switching the air ride system to regular gas shocks. It takes wiring in a relay to fool the body control module, and your ride will be slightly harsher. Check with your local GM dealership for the TSB which contains instructions and the required parts list
