Initial publication
Customer states:
• Front and/or rear doors cannot be opened or closed in freezing weather.
Workshop findings:
• The windows are frozen to the outer window slot seals. The windows cannot drop when trying to open/close
the doors.
• The window auto-drop function is inoperative due to snow and ice build-up.
Technical Background
If snow and ice collect on the windows and the outer window slot seals, the function that lowers/raises the
windows when opening/closing the doors may not operate, even if the window slot seal is of the latest generation.
In freezing weather, the window auto-drop function can be blocked by snow and ice building up between the
windows and the outer window slot seals (Figure 1).

Due to snow and ice adhesion the window and window slot seal can be bonded, resulting in a blockage that can
render the window auto-drop function inoperative (Figure 2).
