Switch, MULTIFUNCTION, Right: Description
The right (wiper) multifunction switch (3) is integral to the Steering Column Control Module (SCCM) (2), which includes the left (lighting) (1) a microcontroller and the clockspring (4). The right multifunction 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 connections are concealed within the SCCM beneath the steering column shrouds. The switch 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 right (wiper) 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 knob provides detent switching for two continuous front wipe modes, low speed or high speed.
- Intermittent Front Wipers - The right multifunction switch control knob provides detent switching for the intermittent front wipe mode with four minor detent delay interval positions. The four delay positions become four sensitivity positions for vehicles equipped with the optional automatic wiper system.
- 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 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 multifunction switch control stalk provides momentary switching for control of the front washer system operation.
- Intermittent Rear Wipe Mode - The right multifunction switch control sleeve 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 right multifunction switch cannot be adjusted or repaired. If any function of the switch is ineffective, or if the switch is damaged, the entire SCCM, clockspring and the multifunction switch unit must be replaced. Refer to MODULE, STEERING COLUMN CONTROL (SCCM), REMOVAL .
