travel auto-leveling on blink

[doug nichols]

When i put the tranny in drive the hwh green travel light comes on but the leveling doesn't. I can manually raise or lower the suspension which makes me think it's the brain or a fuse. Any thoughts? Summer travel at hand.

We recommend that the electric solenoid valves on the automatic leveling system be changed or rebuilt every three years. If this maintenance has not been performed, it is a likely culprit. Once you have confirmed that these valves are operating correctly, we suggest you check the height control valves on the axles.
