Operating Modes

The components of the front wiper and washer system are designed to work in concert to provide the following operating modes:

• Automatic Wipe Mode  - In models equipped with the optional automatic wiper feature, the internal circuitry of both the right (wiper) multi-function switch, the rain sensor module, and the BCM work in concert to provide an automatic wiper mode with five sensitivity selections. When selected, this switch position will automatically operate the front wipers at the programmed speed and intervals to maintain visibility through the windshield glass.
• Continuous Wipe Mode  - The control knob on the control stalk of the right (wiper) multi-function switch has two continuous wipe positions, Low and High. When selected, these switch positions will cause the two-speed front wiper motor to operate in a continuous low or high speed cycle.
• Headlamps On With Wipers Mode  - The BCM provides an automatic headlamps on with wipers feature for models equipped with the optional automatic headlamps. This is a customer programmable feature. If this feature is enabled, the headlamps will turn on automatically whenever the windshield wipers are turned on; and, if the headlamps were turned on automatically when the wipers were turned on, they will also turn off automatically when the wipers are turned off. If this feature is enabled in models equipped with the optional automatic wiper feature, when the automatic wiper mode is selected the headlamps will turn on automatically only after the wipers complete three automatic wipe cycles within about thirty seconds, and they will turn off automatically after three minutes elapse without any automatic wipe cycles. (Refer to ELECTRONIC VEHICLE INFO CENTER ).
• Mist Wipe Mode  - The control stalk of the right (wiper) multi-function switch has a momentary Mist position. When selected, this switch position will operate the front wipers in a low speed continuous cycle for as long as the switch is held closed, then will complete the current wipe cycle and park the front wiper blades near the base of the windshield when the switch is released.
• Speed Sensitive Intermittent Wipe Mode  -Except on models equipped with the optional automatic wiper system, the internal circuitry of both the right (wiper) multi-function switch and the BCM work in concert to provide an intermittent wipe mode with five delay interval selections. When this mode is selected, the BCM automatically adjusts each of the five manually selected delay intervals between complete wipe cycles to compensate for vehicle speed.
• Washer Mode  - When the momentary front wash position of the control stalk for the right (wiper) multi-function switch is selected with the front wiper system operating in a continuous wipe mode, washer fluid will be dispensed onto the windshield glass through the washer nozzles for as long as the washer switch is held closed. When the front washer switch is actuated with the front wiper system operating in an intermittent wipe mode, washer fluid is still dispensed until the switch is released; however, the front wipers will operate in a low speed continuous cycle from the time the washer switch is closed until several wipe cycles after the switch is released, before returning to the selected intermittent wipe mode.
• Wipe-After-Wash Mode  - When the momentary front wash position of the control stalk for the right (wiper) multi-function switch is selected with the front wiper system turned Off, the internal circuitry of the BCM provides a wipe-after-wash feature. When selected, this feature will operate the front washer pump/motor and the front wipers for as long as the front washer switch is held closed, then provide several additional wipe cycles after the switch is released before parking the front wiper blades near the base of the windshield.
