• Q: How to service and repair the headlamp dimmer switch on the steering column multifunction switch on 2009 Mercury Grand Marquis?

  A: The process for repairing the headlamp dimmer switch on the steering column multifunction switch begins with removing the steering column tilt release lever/handle.
