Anti-Pinch Motor Reset Note

This regulator is supplied without a motor. If used with an electric motor featuring an anti-pinch function, the motor may require resetting after installation.

General reset procedure (for compatible one-touch systems):

• Install the motor on the regulator and connect the one-touch window switch.
• If the window drops slightly after reaching the top, a reset is required.
• Briefly pull the window switch up to move the glass fully to the top.
• Hold the switch up for 3–5 seconds at the top position.
• Briefly press the switch down to move the glass fully to the bottom.
• Hold the switch down for 3–5 seconds at the bottom position.
• Pull the switch to raise the window; if it stays at the top, the reset is complete.

Repeat the above steps if the window still drops after reaching the top.

Important Notes

• For repair and replacement use only.
• Images are for reference; actual product colour and finish may vary slightly.
• Always match the part visually and by OE number 51357140589 before ordering.
