I have no air to the rear air bags. the front is ok. Tank pressure is 125lbs and the dump
valves work ok. The rear height controller works if I supply external air.
It's hard to tell where the air lines go. Do you know where the solenoids and/or check valves would be located? Unfortunately driving it is how I discovered the problem.
