If you want to service the headlamp dimmer switch, first make sure the SRS system will not trigger by isolating the battery negative port, disconnecting it and extending the disconnect for two minutes. The first step is to take away the knee blocker on the instrument panel and then come off the upper and lower shrouds that are clamped to the steering column. Following this, separate the instrument panel wire harness connector from the rear of the multi-function switch housing. At the left end of the
Clock Spring, press and hold down on the tab of the latch feature on the multi-function switch housing to unengage it. After unlatching the battery, lift the switch on the receptacle, keeping it clear of the bracket.
