If the battery is properly connected with adequate
voltage, the switch is not disabled, and the liftgate still
will not function, your vehicle should be taken to a
dealer/retailer for service.

beneath the vehicle on the side in which the door
has been opened. Once the door is closed, the running
boards will automatically move back under the vehicle
after a brief delay. The vehicle must not be moving
for the running boards to extend or retract.The switch used to disable
the power running boards
is located on the center
console below the climate
control system.
The running boards cannot be disabled in the extended
position.
