ZAPOSTS Power Window Master Switch for Mercedes‑Benz C‑Class & GLC Driver Side, 3‑Pin 0 AUTO Fit (2015–2022)

ZAPOSTS Power Window Switch is a direct-fit driver-side master switch replacement engineered to match OEM connectors and restore full window control for compatible Mercedes‑Benz C‑Class and GLC models.

If your driver door master switch has failed or the window controls are intermittent, this ZAPOSTS replacement offers the same mounting points, 3‑pin connector layout and 0 AUTO front rocker design found on the original unit. It is designed to replace OEM part numbers including 2059056811, A2059056811 and 2229056800 for the listed C300, C350e, C400, C43 AMG, C63 AMG, C63 AMG S and various GLC models between 2015 and 2022. Confirm vehicle compatibility and visual match to the original switch before purchase to ensure a smooth plug‑and‑play swap.

Will this switch physically fit my Mercedes‑Benz driver door?

Check both the vehicle model/year list and the switch shape on your original part. The ZAPOSTS unit is built to the same footprint and uses the same three-pin rear connector as the factory switch, but visual verification is required.

• Fitment covers C300 (2015–2021), C350e (2016–2018), C400 (2015), C43 AMG (2017–2021), C63 AMG and C63 AMG S (2015–2021).
• Also fits GLC300 (2016–2021), GLC350e (2018–2019), GLC43 AMG (2017–2022).
• Compare the front face (0 AUTO marking) and the back connector (3 pins) to your original switch.

How do I replace the master window switch safely?

Turn the vehicle power off and remove the door trim as needed to access the switch. Align the switch housing carefully with the socket and plug it in straight to prevent bent pins or poor electrical contact.

• Disconnect battery or turn off power before starting work.
• Ensure the plug aligns and inserts fully to avoid pin deformation.
• Reassemble trim and test all window and lock functions before finishing.

Which OEM part numbers does this unit replace and why check them?

The ZAPOSTS replacement lists multiple OEM numbers to cover variations between production runs and trim levels. Matching the OEM number on your original part guarantees compatibility and prevents surprises during installation.

• Replaces 2059056811, A2059056811, 2229056800, A2229056800 and A20590568119051.
• Confirm the number stamped on your old switch or compare images closely before buying.
• If unsure, contact seller support with photos of your original switch for confirmation.

What should I expect after installation—will controls behave like original?

When the connector and switch face match, the replacement restores full driver‑side control including window roll, auto‑up/down behavior (where applicable) and mirror/lock inputs that tie into the same circuit. Functional parity depends on correct wiring and a properly seated connector.

• Expect identical button arrangement and 0 AUTO marking on the front rocker.
• Properly seated 3‑pin connection ensures reliable electrical contact.
• Test each window and lock function immediately after installation.

Who is this for: This ZAPOSTS master power window switch is intended for Mercedes‑Benz drivers, DIY mechanics and professional technicians seeking an affordable, direct replacement for a worn or failed driver door switch on compatible C‑Class and GLC models. It’s best for buyers who can verify their original part visually or by OEM number and who want a plug‑and‑play solution that matches factory fit and function.
