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).

Figure 1. Snow and ice build-up on window and window slot seal surfaces.
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).
