Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The windshield wiper motor receives a ground signal from the multi-function switch through circuits 56 (DB/OG), 58 (WH), 61 (YE/RD), and 63 (RD). When a wiper function is selected, the multi-function switch grounds 1 of several combinations of these 4 circuits. The windshield wiper motor interprets these ground signals and performs the action requested. The multi-function switch is grounded through circuit 57 (BK).
