Check the wires on the cables going to the controller on the drawer slide, WRV besides being infamous for long wires is also infamous for short wires on that cable, the connections break VERY easily!
Normal operation of the system is to take about 2 minutes to dump the air bags then lower the jack that is on the lowest corner, the proceed with the rest of the jacks, then shut off. The system will NOT work if the parking brake is not set.
Do you get a "Park" light on the dash?
Do you get any lights on the HWH panel, which ones and what is the model number of the panel?
Does the system operate properly in all other aspects including after starting the auto leveling, give it about 2 minutes does it extend the jacks?
Can you raise and lower the jacks manually?
Can you extend the slides?
