I have the same problem !!!!!
did you solve yours?
what was it ???

Same problem here as well. Does anybody know what to try??

check the compressor relay.The compressor relay is mounted on a bracket located at the center of the radiator support rail.

I have power at the switch in the trunk, but not at the compressor. I can power up the compressor by hot wiring it. It runs and pressurizes the lines, BUT, whatever tells the valves to open at each corner of the car, is not working. I cannot believe all 4 of the individual level switches went bad all at once, so what else tells the valves to open to let air into the suspension? Any clues???

i know this can be hard but try following the line that powers the compressor and check it for a possible fusable link somewhere.....if everything is working but that power line to the compressor then it could be the line itself.

The switches your refering to are the ride hight sensors and they can go bad when road debris gets kicked up and hits them and breaks or knocks them loose..you will know by looking at them.. see if they are attached to the suspension at the base of the sensor...i would check them to make sure the rods comming out of them are attached....if there not it could cause the system to think its allready at ride hight and not turn the compressor on or vise versa.

I think the power supply line is OK.. I found that if I turn teh switch in the trunk on and off, the pump will occasionally run. The level sensors are all intact, and I have air pressure at the line were it goes into the valve assy. But, whatever tells that valve to open, is not doing its job. Any other ideas?? THANKS
