Multifunction Switch
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The multifunction switch controls the various components electrically. The multifunction switch is hardwired to the SJB and controls a ground signal for the high beam, flash-to-pass and turn signal functions. The multifunction switch is also hardwired to the wiper module and controls a ground signal for the various wiper and washer functions.
For headlamp and turn signal concerns, refer to EXTERIOR LIGHTING -- FUSION, MILAN & MKZ article. For wiper and washer concerns, refer to WIPER SYSTEM & WASHER SYSTEM -- FUSION, MILAN & MKZ article.
