Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Overheating Protection of Power Window Motors
The footwell module and the junction box electronics monitor the motor temperature. The motor temperature is determined based on the outside temperature, motor running time and the time the motor is stationary (not operative). Each motor can be switched off individually to prevent the power window motors overheating during operation of the power windows. The motor is then deactivated for a defined period of time.
The overheating protection facility does not prevent the windows being opened in the case of trapping. Once started, a power window function is not interrupted by the overheating protection facility. In panic mode the window can still be closed even when the overheating protection function is active.
