How to Install Power Folding Tow Mirrors on 2005 GMC Sierra rant.li

If you purchased power folding mirrors, you need to install the new switch panel. Remove the factory mirror adjustment switch from the driver's door armrest. Unplug it and plug in the new switch panel that includes the power fold button. Connect the wire you ran from the mirror to this switch. Route the wiring carefully to avoid interference with window mechanisms. Test the power fold function before reassembling the door panel. The mirrors should fold inward simultaneously when you press the button. Some kits also include auto-fold on lock/unlock, which requires additional wiring to the door lock actuator.
