Steering Wheel Switches
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The RH steering wheel switches are rocker-type momentary contact switches that contain a series of resistors. Each steering wheel switch function corresponds with a specific resistance value within the switch.
The switches are only replaceable as a complete unit.
