Right Multi-Function Switch: Description
The right (wiper) multi-function switch is located on the right side of the steering column, just below the steering wheel. This switch is the primary control for the front and rear wiper and washer systems. The only visible components of the switch are the control stalk (1), control knob (2) and control sleeve (3) that extend through the steering column shrouds on the right side of the column. The remainder of the switch including its mounting provisions and electrical connection are concealed beneath the shrouds.
The switch housing (2) and controls are constructed of molded black plastic. Each of the switch controls has white International Control and Display Symbol graphics applied to it, which clearly identify its many functions. A screw through each of two mounts integral to the switch housing, one each at the top and the bottom, secure the switch to the Steering Control Module (SCM) (4). A single integral interface connector with nine terminal pins is integral to the switch housing and connects the switch directly to the SCM.
The right (wiper) multi-function switch provides the vehicle operator with a control interface for the following wiper and washer system functions:
- Automatic Front Wipers - For vehicles so equipped, the right multi-function switch control knob provides detent switching for the optional automatic front wipe mode with five minor detent sensitivity positions.
- Continuous Front Wipers - The right multi-function switch control knob provides detent switching for two continuous front wipe modes, low speed or high speed.
- Intermittent Front Wipers - The right multi-function switch control knob provides detent switching for the intermittent front wipe mode with five minor detent delay interval positions. On vehicles that have the optional automatic wiper system, the automatic front wipe positions of the control knob provide default intermittent wipe mode operation whenever the automatic system has been disabled using the customer programmable features option in the Electronic Vehicle Information Center (EVIC).
- Front Wiper Mist Mode - The right multi-function switch control stalk includes momentary switching of the front wiper motor low speed circuit to provide a mist mode features (sometimes referred to as pulse wipe), which allows the vehicle operator to momentarily operate the front wipers for one or more complete cycles.
- Front Washer Mode - The right multi-function switch control stalk provides momentary switching for control of the front washer system operation.
- Continuous Rear Wipers - The right multi-function switch control sleeve provides detent switching for a single continuous rear wiper mode.
- Intermittent Rear Wipe Mode - The right multi-function switch control sleeve provides detent switching for a single fixed interval intermittent rear wiper mode.
- Rear Washer Mode - The right multi-function switch control sleeve provides two momentary switch positions for control of rear washer system operation.
The right multi-function switch cannot be adjusted or repaired. If any function of the switch is ineffective, or if the switch is damaged, the entire switch unit must be replaced.
