Adjust your power outside mirrors from the door with the Standard Ignition switch MRS163, a door-mounted remote mirror switch that sends your mirror-adjustment commands to the power mirrors. It is a direct-fit OE replacement for the 2013-2018 Cadillac ATS, 2014-2015 Cadillac SRX, and 2016-2019 Chevrolet Impala. Engine and trim details for each application are listed in the "Vehicles it fits" section.
Signs this switch may need replacing include a power mirror that will not move in one or more directions, a mirror that responds only intermittently, or controls that feel unresponsive. A mirror motor or wiring fault can produce similar symptoms, so diagnose the cause before replacing the switch. If a worn or failed remote mirror switch is the cause, MRS163 replaces it.
