Here is the scenario...coach was parked for 3 months rear leaked down front OK. Started the engine and right rear would not raise all 3 other corners OK. Dumped air in the rear (4 bags) and let it air back up came right up to travel height. Soooo..my question is travel solenoid, raise solenoid or ???
Help appreciated. this has happened intermittently for about 8 months now
Thx

If you're in "travel mode" on the control panel, then it's the travel solenoid that you need to look at. It could be sticking. The "raise" solenoid will be closed in that situation and probably isn't the culprit.
I would start by inspecting the ride height control valve for that corner though, since it's easier to get to and visually troubleshoot. If that looks good then it's probably time to rebuild your rear six pack and verify that the solenoid in question is consistently engaging when given 12v.
Ride height valve would not be intermittent .
Could also be a ground issue if raise command in manual does not work also
Amazing your fronts did not leak down after 3 months! Mine don't even go more than a week or two!
I would swap the rear travel solenoids. If the problem moves over you found it. If the problem doesn't move I would start looking at the wiring. Magic box next.
