Review on Front Power Running Board Motor with Bracket | Fits 2007-2014 Ford Expedition & Lincoln Navigator | 119.0 Inch Wheelbase | Replaces 9L7Z16A506A 9L7Z16A507A | Part Number 747-900 by Doug Virden

The footrest motor controls the footrest. The side stand can protect vehicles from various types of road debris. When the chassis is not high enough when going through a deep ditch and a steep slope, the bottom of the pedal touches the ground for the first time and emits a friction sound as a warning to protect the chassis from injury. It also takes on the same role when driving through a very narrow traffic safety bridge by directly securing the door and side walls.
