2009 Chevrolet Tahoe Base, 4.8 CSECTION Circuit/System Description
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The rear wiper is controlled based on an input from the rear wiper/washer portion of the multifunction switch. When the switch is in the ON or DELAY, a voltage signal is sent to the rear window wiper motor indicating the desired speed. Each switch position has resistor that drops the voltage to a specified value which is interpreted by the rear window wiper motor as ON or DELAY.
