Technical characteristics of the side window

As an element from the Car windows category, the front left side door window performs several key technical functions:

• maintains proper sealing of the door system, limiting noise, drafts, and moisture ingress,
• guarantees stable operation with the window lifting mechanism, both manual and electric,
• maintains compatibility with factory seals and trim strips.

The AS2 standard means that the window meets the light transmission requirements for side windows, which is important both from a regulatory perspective and for the comfort of the driver and passengers.

Component condition and service application

The offered window is a used part, making it an attractive service solution for post-accident repairs or replacing a damaged window in a Mercedes W168.

Replacing a side window is a typical bodywork or service procedure following mechanical damage, break-ins, or cracks resulting from wear and tear.
