Description And Operation: Description
The wiper (right) multifunction switch (2) is located on the right side of the steering column, just behind 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 with a control knob and control sleeve that extend through the steering column shrouds on the right side of the column. The remainder of the switch including its mounting provisions and its electrical connection are concealed beneath the shrouds.
The switch housing 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. The wiper (right) multifunction switch for this vehicle is integral to the Steering Column Control Module (SCCM) which also includes an integral lighting (left) multifunction switch (1) and the clockspring (3).
The wiper (right) multifunction switch provides the vehicle operator with a control interface for the following wiper and washer system functions:
- Continuous Front Wipers - The right multifunction switch control stalk provides detent switching for two continuous front wipe modes, low speed or high speed.
- Intermittent Front Wipers - The right multifunction switch control stalk provides detent switching for two speed-sensitive intermittent front wipe modes.
- Front Wiper Mist Mode - The right multifunction switch control stalk includes momentary switching of the front wiper motor low speed circuit to provide a mist mode feature (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 multifunction switch control stalk provides momentary switching for control of front washer system operation.
- Continuous Rear Wipe Mode - The right multifunction switch control knob provides detent switching for a single continuous rear wiper mode.
- Intermittent Rear Wipe Mode - The right multifunction switch control knob provides detent switching for a single fixed interval intermittent rear wiper mode.
- Rear Washer Mode - The right multifunction switch control stalk provides momentary switching for control of rear washer system operation.
The wiper (right) multifunction switch cannot be adjusted or repaired. If any function or feature of the switch is ineffective or if the switch is damaged, the entire SCCM must be replaced. Refer to MODULE, STEERING COLUMN CONTROL (SCCM), REMOVAL AND INSTALLATION .
