Right Multi-Function Switch: Description
The right (wiper) multi-function switch is secured to the right side of the multi-function switch mounting housing at the top of the steering column, just below the steering wheel (Fig 1 ). The only visible component of the right multi-function switch is the control stalk that extends through a dedicated opening in the right side of the steering column shrouds. The remainder of the right multi-function switch is concealed beneath the steering column shrouds. The switch housing and its control stalk are constructed of molded black plastic. A single connector receptacle containing up to ten terminal pins is located on the back of the switch housing and connects the switch to the vehicle electrical system through a take out and connector of the instrument panel wire harness. The switch is secured to the multi-function switch mounting housing near the top of the steering column by two screws.
There are two versions of the right multi-function switch: one to support the standard equipment speed sensitive intermittent front wiper system, and a second to support the optional front automatic wiper system. Each version of the right multi-function switch control stalk has both white nomenclature and International Control and Display Symbol icons applied to it, which clearly identify its many functions. The control stalk has a control knob on its end with a flattened face to allow it to be easily rotated. Just below the control knob is a knurled control sleeve. The right multi-function switch is the primary control for the front and rear wiper and washer systems, and contains switches and circuitry to provide signals to the Body Control Module (BCM) and the rear wiper module.
The right (wiper) 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.
The right (wiper) multi-function switch supports the following functions and features:
- Automatic Front Wipe Mode - On models equipped with the optional automatic wiper system, the internal circuitry and hardware of the right (wiper) multi-function switch control knob provide an automatic front wipe mode with five sensitivity positions.
- Continuous Front Wipe Modes - The internal circuitry and hardware of the right (wiper) multifunction switch control knob provide two continuous front wipe switch positions, low speed or high speed.
- Continuous Rear Wipe Mode - The internal circuitry and hardware of the right (wiper) multifunction switch control sleeve provides one continuous rear wipe switch position.
- Front Washer Mode - The internal circuitry and hardware of the right (wiper) multi-function switch control stalk provide front washer system operation.
- Front Wipe-After-Wash Mode - The internal circuitry and hardware of the right (wiper) multifunction switch control stalk provide a wipe-after-wash mode.
- Front Wiper Mist Mode - The internal circuitry and hardware of the right (wiper) multi-function switch control stalk provide a front wiper system mist mode.
- Intermittent Front Wipe Mode - The internal circuitry and hardware of the right (wiper) multifunction switch control knob provide an intermittent front wipe mode with five delay interval positions, except on models equipped with the optional automatic wiper system.
- Intermittent Rear Wipe Mode - The internal circuitry and hardware of the right (wiper) multifunction switch control ring provide one fixed interval intermittent rear wipe mode switch position.
- Rear Washer Mode - The internal circuitry and hardware of the right (wiper) multi-function switch control stalk provide rear washer system operation.
