ZAPOSTS Power Window Switch is a direct-fit driver-side master window control designed to replace worn or faulty OEM part 2059056811 in compatible Mercedes‑Benz C‑Class and GLC models.

This replacement unit restores power window and mirror control functions for the driver door on select Mercedes‑Benz C300, C350e, C400, C43 AMG, C63 AMG, C63 AMG S and GLC models from model years shown. It reproduces the original switch’s plug configuration and pin count so installation is straightforward when the vehicle and original part match the product images and listed part numbers. Before ordering, verify vehicle fitment and compare the front face and rear connector of your original switch to ensure full compatibility.

Will this switch fit my Mercedes‑Benz model?

If your vehicle is listed among the compatible models, this ZAPOSTS assembly is intended as a direct replacement, but fitment depends on matching the original switch’s connector type and front face layout. Check both model year and the physical appearance of your existing switch before purchase.

• Compatible models: C300 (2015–2021), C350e (2016–2018), C400 (2015), C43 AMG (2017–2021), C63 AMG/C63 AMG S (2015–2021).
• Also fits GLC300 (2016–2021), GLC350e (2018–2019), GLC43 AMG (2017–2022).
• Compare the front face: unit must match the pictured layout including the 0 AUTO marking on the front control.
• Confirm the rear connector: the replacement uses the same 3‑pin configuration shown in product photos.

How do I confirm the part number and connector match?

Locate the part number stamped on your original switch or compare against the OEM numbers provided. Matching the correct part number and connector prevents electrical faults and ensures the replacement performs like the original unit.

• Replaces these part numbers: 2059056811, A2059056811, 2229056800, A2229056800, A20590568119051.
• Compare the rear housing and verify the three pins align with your vehicle socket.
• Use the product photos to confirm front face features and button arrangement.

What should I know about installation and safety?

Installation is a straightforward electrical swap but requires caution: disconnect vehicle power and align the connector to avoid bending pins. Proper seating of the plug ensures reliable contact and prevents intermittent operation.

• Turn off vehicle power before beginning the replacement.
• Align the switch to the socket and insert straight to prevent pin deformation.
• Verify the plug is fully seated and that the switch retains firmly in the door trim.

What practical features does this replacement provide?

The switch restores central driver-side control for power windows and mirrors, matching the factory look and function so the cabin controls behave as intended. It’s made to fit the same mounting and electrical setup as the original for a clean, low‑profile installation.

• Factory-style appearance that integrates with original door trim.
• Full driver-side master control for all windows and mirror adjustments (where applicable).
• Predefined connector and pin layout for direct replacement compatibility.

Who this is for: This ZAPOSTS replacement suits DIY owners, independent mechanics and restoration shops working on supported Mercedes‑Benz C‑Class and GLC models who need an OEM‑style driver door master switch.
