check to see if the sensor link/arm as still attatched in the rear of the car. it has a little plastic ball end on each end and the ball can rust and fall off so the pump stays running. you can unplug the compressor to stop the dead battery condition for now. there is some diagnosis involved in repairing it though.

SOURCE: falty air compressor

It could be in one of two places. They did mount an air pump under the alternator, (looks like the air pump for pollution control or it could be mounted near the rear axle if it is an electric one. I am not sure which one you would have so jack up the rear (safety first, use wheel chocks) and trace the air lines off the shock back to the source. I hope this helps you and good luck.

Air suspension will not work. i changed the leveling ride switch and checked all the fuses?


The compressor may be locked up or you may have an air leak. Look at each shock absorber to see id an air line has become disconnected. This will let all the air out of the system.

HOW DOES BUICK LEVELING COMPRESSOR WORK?


It uses sensors to determine level of car and activates the compressor to level it to the preset settings in the control modules memory. The common problem is that the air suspension bags leak after about 75,000 miles of use. As for wiring diagrams we have none due to copyrighted material. You can find all that you need in the factory manuals, you can buy access here.

I have a 95 pakk ave. with daynatrac is the compressieor supposed to come on alot when the car to not running?


If we are talking about the Air suspension compressor the answer is NO. If the compressor has to run alot, then there is a leak in an air line or suspension bag or other component.

You can take an old spray bottle of soapy water and you would have to go underneath the car and spray the components Where you would see bubbles would indicate a leak.

There should be a Diagnostic plug for a computer hook-up to read the Air-suspension computer. This will tell you if any switches are bad. You would need to go to a shop having the tools capable of reading your system. Not all scanners are alike and only the more expensive scanners have this function.

EXPEDITION REAR AIR RIDE PROBLEM


do you have just rear air suspension? here's rear only. 4 wheel different. Deler an run a diagnostic test with WDS machine and get fault codes.
-------------------------------------------------------------------------------------
The air suspension system is designed to improve ride, handling and general vehicle performance for static, on-road and off-road driving conditions:
  • Ride is improved by using an air type spring (the soft ride is inherent).
  • Handling is improved by maintaining constant vehicle attitude.
The system consists of unique rear air springs, the air compressor, air lines, air spring solenoids, height sensor, air suspension control module, attachments and associated signals derived from both driver and road inputs. With these components and signals, the air suspension control module commands changes in vehicle height that are necessary for the load leveling features.
The load leveling feature rear air suspension (RAS) systems shall automatically make adjustments in vehicle height so that the vehicle is always at trim height and constant front-to-rear vehicle attitudes are maintained over the expected load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle's left and right sides for the RAS system shall be restricted to what can be reliably achieved with one air suspension height sensor.
The system uses one air suspension height sensor, a steering sensor, generic electronic module (GEM) and other vehicle sensors to measure driver and road inputs. The system changes vehicle height using an air compressor, two air lines and the use of air springs with air spring solenoids.
The air suspension system holds vehicle height when the rear hatch or any door is opened. The system stores rear vehicle height the moment any open door is detected. The system then maintains this height regardless of the addition or removal of a load. The system will return to its commanded height when all doors are closed or the vehicle speed exceeds 16 km/h (10 mph).
----------------------------------------------------------------------------------------
Air Suspension Height Sensor
One air suspension height sensor is mounted on the vehicle. The air suspension height sensor sends a voltage signal to the air suspension control module. The output ranges from approximately 4.75 volts at minimum height (when the vehicle is low or in full jounce), to 0.25 volts at maximum height (when the vehicle is high or in full rebound). The air suspension height sensor has a useable range of 80 mm (3.2 in) compared to total suspension travel of 200-250 mm (8 to 10 in) at the wheel. Therefore, the air suspension height sensor is mounted to the suspension at a point where full rear suspension travel at the wheel is relative to 80 mm (3.2 in) of travel at the air suspension height sensor. The air suspension height sensor is attached between the No. 5 frame crossmember (upper socket) and the panhard rod (lower socket).
When the air suspension height sensor indicates that the rear of the vehicle is lower than trim under normal driving conditions, the air compressor will turn on and pump compressed air to the air springs. When the sensor indicates that the rear of the vehicle is raised above trim under normal driving conditions, this will cause the air to be vented from the air springs to lower the vehicle back to its trim height level
------------------------------------------------------------------------------
  • Uneven vehicle height
  • Circuitry.
  • Rear pneumatic fault.
  • Air compressor assembly.
  • Air suspension control module.

Location of air ride pump


it should be right under the hood (follow the small air lines to it)
If it is not there , then they hide them under the rear quarter panel on some models.
Follow the lines from the shocks to it .

There are ride height sensors in the rear that send a signal to the ride height/load leveling control module, one of these ,may be defective. Have Ford dealer run an active test of the system, they will find out what the part is that has failed, otherwise you are guessing, that equals wasted $$$
