Have you had the vehicle scanned to see what code the system is giving you? I would start there. You can check the bag for leaks by using soap and water and spraying the bags down and check for air bubbles at source of leak. Sometimes they can be very slow and hard to find. However I would start with codes. It may not have anything to do with a leaking air bag.
Update . I havent been able get code. I ran truck compressor come on. The rear dont come up.. i spry air line and connection to comppressor and rear. No leaks.
I spray compressor.
Were i do her some leak sound is by the compressor.I belive the compressor is piston in side. Can somehow. It run but no air actually come out.
I dont know were else to check.
I dont think is the rely cause compressor turns on. Not the leveling sensor cause it detect is low. Line look ok
Any ideas
