Common problems of window lifter:

The original W205 Benz C-Class cars adopt a window lifter based on an integrated rail and door panel design, with diagonal pulling wires in direct contact with the door panel. During driving, accumulated mud, sand, and other dirt can increase the friction between the wires and the door panel, thus causing wear and abnormal lifting noise.

Advantages of DPA window lifter :

1. Redesigned guide rail guide groove：An outer tube is added.

2. Use 7*8+1 strands pull wire: Increase pulling force (OE: 7*8+1 strand).
