Temperature Protection For Power Windows

Temperature Protection For Power Windows

To prevent thermal overload of the power window motor, temperature protection (cycle protection) is installed.

Operating principle
This temperature protection is enabled whenever the window is opened and closed 4 to 10 times in quick succession.
The window can then only be closed and is then disabled for 8 to 10 minutes.
After this cooling-down period, the power window drive can again be used normally.
The precise behavior (maximum number of operations and disengagement duration) depends on the vehicle voltage and the programmed control unit software.
