A friend who works for Rancho set me up with their air shocks that are controlled from the cab with a frame mounted compressor that is controlled by a button inside the truck. Air to the shocks is controlled via a button mounted on the dash to stiffen the ride and two additional buttons release the air (front and back) to soften the ride.
After a year the system doesn't work. I checked power at the fuse box and it appears to be okay.
The system worked pretty well when installed but now I'm stuck with four shocks that I can't adjust. On top of losing the ability to add air, the shocks have turned black with rust.
Does anyone else have this setup? If so any ideas on how to fix the issue?
