Mist Operation
In the MIST position, voltage is supplied through a internal 562 Ω resistor to the signal circuit of the windshield wiper/washer switch for the BCM. The BCM will momentarily energizes the Wiper 1 relay which will operate the windshield wiper motor at low speed.
The windshield wipers make one sweep at low speed and returns to the park position. If the windshield wiper/washer switch is held in MIST mode, the windshield wipers will continue to operate until the switch is released.
