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.
Anti-repeat circuit
An anti-repeat circuit is provided for each motor to prevent the power window motors from overheating. The running time for the power window motor is limited. The motor is switched off for a defined time.
The anti-repeat circuit permits at least five complete window movements (OPEN/CLOSE).
The last possible movement is always a closing process.
If something becomes trapped, the anti-repeat circuit will not prevent opening.
The anti-trap circuit always reverses the movement of the side window.
The anti-repeat circuit is integrated in the door modules or in the body basic module.
