Take command of your side-view mirrors from the driver's door with the Standard Ignition Door Remote Mirror Switch (MRS143). This remote mirror switch sends the driver's inputs to the power mirror motors, letting you adjust mirror angle without reaching across the cabin. It's a direct-fit replacement for the 2014-2017 Buick Regal, 2013-2019 Cadillac ATS, 2013-2019 Cadillac XTS, 2015-2022 Chevrolet Colorado, 2014-2019 Chevrolet Corvette, 2014-2019 Chevrolet Impala, and 2015-2022 GMC Canyon — see the "Vehicles it fits" section for engine specifics and the full application list.
- Copper alloy conductors: deliver strong electrical conductivity with low resistive losses.
- Direct-fit OE replacement: matches the original's fit, form, and function for straightforward installation and proper restoration of power mirror operation.
- Robust design and high-grade materials: built to meet stringent quality standards.
- Global quality control: maintained throughout the manufacturing process.
If the original switch is the cause of mirrors that no longer respond, respond intermittently, or only move in certain directions, this replaces it. Diagnose the cause before replacing to rule out wiring, the mirror motors, or connectors.
