Mercedes W177 Seat Heater Switch Left Front 2019-2023 A1779056700 A220 CLA
Mercedes-Benz seat heater switch assembly for the left front / driver-side seat control area. Compare the switch shape, connector and part number against your existing unit before purchase.
Mercedes-Benz heated seat switch
Part number cross-reference: A1779056700 / 177-905-67-00-9107. The catalog sources I checked show this switch family fitted to select Mercedes-Benz models from 2019-2023, with specific model coverage listed below.
Why replace it: a faulty seat heater switch can cause inoperative heated seats, intermittent heat, dead indicator lights, worn or sticky buttons, or only partial operation. Replacing the switch restores the correct control input to the heated seat system.

Why choose the correct part first time

A matched used part gives the best value: exact shape, exact connector and exact control function, without paying new-part prices. That helps reduce returns and keeps the vehicle original in operation.

✔ Better fit when the part number matches
✔ Saves money versus a cheap copy
✔ Helps avoid dashboard warnings and compatibility issues
