Mist Operation

Windshield Wiper/Washer System mist operation is identical to low operation, except that the mist switch is a press and release type switch. When the wiper switch is moved to the mist position and released, low speed wiper motor operation is started and will continue until 1 cycle is complete. If the wiper switch is moved to the MIST position and held, the wiper motor will operate in the LOW mode until the switch is released.

In the MIST position, voltage is supplied through an internal resistor to the signal circuit of the windshield wiper/washer switch for the body control module (BCM). The BCM will energize the wiper micro relay which will operate the windshield wiper motor at low speed.
