When the car wants to fill (raise up), it opens both air spring solenoids and powers the compressor motor, but the vent solenoid on the compressor remains closed. 1 on top of each air spring, and one on the compressor assembly. There are 3 solenoids in the air suspension. The system stays active for up to an hour after the ignition is switched off, beyond that it should hold everything closed. When it vents, it does so by letting air out at the front via the vent solenoid that is integrated into the compressor assembly. When it senses the car is sitting too high, it will vent. If it sinks down while it sits, then the leak has to be in the rear bags, the solenoids, or the o-rings that go between the bags and solenoids. The lines and compressor could be totally removed from the car, as long as it doesn't command those solenoids open it'll stay at ride height. The solenoids that sit on the bags seal them off, think of it like the knot on a balloon, except it opens up when the car tries to fill or vent air into/out of the springs. You have to remember that the system is sealed when it is not actively venting or filling the springs(bags). I am 100% going to fix this system not replace it will springs. The Air Motor stays on for awhile sometimes fills, but it will come back on and eventually the AIR SUSP light comes on and stops turning on the motor till a key ignition cycle happens. How can I test such a thing? spray water down on the motor? so I am totally guessing the leak is right at the motor not the balloons in back. ![]() I can see and make what looks like the pump wiggle from the air box attached to it. The rubber grommets on the motor corroded out a year ago, so the motor has been banging around loudly for that long, I replaced one with some old rubber by jamming it in there but the motor was already looking quite aluminum corroded. before yall point to the balls in the back let me note some more important facts. So anyway I knew the Air Suspension had a slow leak, now it appears to be a quick leak. Ok back to my car really hating not being driven 7 days a week.Įverything is starting to pile up, but ah well I have a 2nd car now so I can leisurely fix crap. ![]()
