Pinpoint Test E: The Steering Wheel Control Switch(Es) Illumination Is Inoperative

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
  1. E1 CHECK THE STEERING WHEEL CONTROL SWITCH(ES) FOR VOLTAGE 
    • Key in OFF position.
    • Remove the driver air bag module. Refer to SUPPLEMENTAL RESTRAINT SYSTEM .
    • Disconnect: Inoperative Steering Wheel Control Switch.
    • Key in ON position.
    • With the parking lamps on, rotate the instrument panel dimmer switch to the maximum brightness level.
    • For vehicles equipped with audio/climate control switches, measure the voltage between the speed control switch C203-4, circuit 484 (OG/BK), harness side and ground; or between the audio/climate control switch C2208-1, circuit 484 (OG/BK), harness side and ground.
