FlyU2here: I have the "thing" that sits behind the HWH control Pad. It overrides the HWH.
It will lock the air in what ever position I desire by rotating the dial away from drive position. Return the dial to drive and it goes to ride height by default. Depending on the position of the dial as it relates to front, or LR, or RR and which button you hold down either up or down. I also have a red warning on the dash whenever it is not in the drive position.
It took Truk to show me how to use it after I got the coach.
Roger that!
