I finally got a chance to see if I could fix this problem. I have now determined that if I put the selector switch on the front position I can exhaust the air and the front goes down. Then I tried to raise it from that dumped position by pushing the up switch, nothing. Then if I put the selector switch to the off position the front will come up to, what I believe is, ride height. I removed the rear right solenoid and put it where the front solenoid is then I turned the selector switch to right position, pushed the up switch, nothing. What now, am I missing something?
