DESCRIPTION





The left (lighting) multi-function switch is secured to the left side of the multi-function switch mounting housing at the top of the steering column, just below the steering wheel. The only visible component of the left multi-function switch is the control stalk (3) that extends through a dedicated opening in the left side of the steering column shrouds. The remainder of the left multi-function switch is concealed beneath the steering column shrouds. The switch is secured to the multi-function switch mounting housing near the top of the steering column by two screws.

The control stalk has a control knob on its end with a knurled face to allow it to be easily rotated. Just below the control knob is a knurled control sleeve. The left multi-function switch is the primary control for the interior and exterior lighting systems, and contains switches and circuitry to provide signals to the Body Control Module (BCM).

The left (lighting) multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if the switch is damaged, the entire switch unit must be replaced.

A single connector with eleven terminal pins is located on the back of the switch housing and connects the switch to the vehicle electrical system. The left multi-function switch supports the following exterior lighting functions:

- Auto Headlamps (if equipped)
- Front Fog Lamps (if equipped)
- Headlamps
- Headlamp Beam Selection
- Headlamp Optical Horn
- Park Lamps
- Turn Signal Control

The left multi-function switch also supports the following interior lighting functions:
