ABSTRACT:
A window lift system includes a motor drive assembly (10) constructed and arranged to control movement window glass of a vehicle, and a door module (35) to which the drive assembly is coupled. The door module has surface features (36) disrupting a surface (37) of the door module to reduce the transfer of vibration energy from the door module to the drive assembly or vise versa. In an embodiment, the door module includes a diaphragm (34) and the surface features are annular, undulating, wave-like features in the diaphragm.
