Bad solenoid, leaking bags
Bad compressor? Air leak in system? Excessive vehicle weight?
Likely your system has a leak and the compressor can't keep up with the volume of the leak. <><><> Agree. The air bags in the suspension of ours had developed small holes, and the compressor could not keep up. Get that fixed before the compressor burns out.
there are several causes to the air pump. the first and most obvious is the air pump (compressor) itself. if you do not hear the compressor pumping air or if you do not feel the slight vibration of the compressor when you put your car into drive, then it's probably the compressor that has gone bad. if the compressor is coming on and you do not hear any air leaking, then your problem could be the height adjuster, located on the suspension bags themselves. Bronconvict: another possibility includes the compressor relay switch. This switch controlls the power to the air bag suspension compressor. This switch is known for burning out when the suspension compressor is working too hard. This can also be caused by a bad/corroded GEM module (due to notorious winshield leak). i had to replace "height sensor" on driver side . part was $200.
The shocks could be the problem.
If it has air bag suspension, air bags could be shot or the air compressor for the air bag suspension not working.
Check your owners manual. If you don't have one copy & paste this link. http://www.genuineservice.com/genuineservice/en/gloveboxresults ---------------------------------- a malfunction has been detected with the air suspension system It could mean a number of things, air compressor could be bad, soleniod could be bad, bags could be leaking -- Call Strutmasters they are ready and willing to help you get ride of this problem you are having.
You probably need a new air filter for your a/c The clicking is probably caused by the clutch on the compressor. If the Ac isn't charged enough it could cause this to kick the compressor off and on. You compressor could also be bad. You werent real clear what the problem was. Hope this helps.
Could be one or both of the front air bags or the spider valve in the compressor.
I assume that the switch also turns off the air compressor for the suspension. The effects will not be very clear for the first 5-10min. of driving, but eventually the ride will become more and bumpier because the compressor is not re-pressurizing the system. The suspension will be bottomed out constantly, because there is no air holding the truck up, and the truck will look like a low rider. That's what happened when our 2004's air compressor failed. I could be wrong if it does not turn off the compressor, but if it does, this is what will happen.
Your light control module(LCM) may not be working. I replaced my air suspension system with regular shocks because of this problem. The LCM is a black box almost the size of a vhs tape found underneath the steering wheel.
The problem could be the relay that goes to the compressor this could be faulted out causing the compressor to run constantly. However if this isn't the case then a quick check of the fuse may also resolve the problem.
It means that the compressor is broken inside, and it is time to replace it.
