The liftgate control module provides an output signal to the rear wiper motor for the purpose of disabling wiper motor operation whenever the liftglass or liftgate are open. The liftgate control module receives inputs from the liftglass ajar switch and the sector, ratchet and pawl switches in the latch assembly to determine when an ajar condition exists. The rear wiper inhibit circuit is supplied 12 volts through a resistor and monitored within the wiper motor module. When an ajar condition exists, the liftgate control module drives the rear wiper inhibit circuit low which the wiper motor module determines is an active inhibit signal.
