Windshield Wiper System: Notes

The wiper and washer system functions are activated by the wiper/washer switch which provides an input to the Body Control Module (BCM). The BCM then provides an output to operate the desired wiper system feature. The windshield and rear window wiper systems share the window washer pump and cannot be used simultaneously. The windshield wiper system only operates when the ignition is ON.

The windshield wiper system offers 4 wipe modes:

• Single
• Intermittent (6 settings)
• Normal
• Fast

The wiper system setting of the wiper/washer switch is transmitted to the BCM to actuate the wiper motor and set the wiper speed. Normal wipe speed remains available in the event of BCM failure.
