Standard Ignition Door Remote Mirror Switch P/N:MRS159
If a worn switch is keeping your power mirrors from adjusting, the Standard Ignition switch MRS148 is a remote mirror switch built to take its place. This door remote mirror switch is a direct-fit OE replacement for many vehicles, among them the 2016-2019 Chevrolet Impala, 2013-2017 Cadillac ATS and 2016-2019 Cadillac CTS. See the "Vehicles it fits" section for complete application details.
The remote mirror switch sends your adjustment commands to the power mirror motors, so you can aim the outside mirrors from inside the cabin. Signs this switch may need replacing include mirrors that don't respond, mirrors that move in only some directions, or mirrors that work only intermittently. Wiring, connectors, or the mirror motors themselves can cause the same symptoms. Diagnose the cause before replacing the switch.
