Key Benefits
Direct-fit replacement for the left front window regulator motor. Improves window operation speed and smoothness, prevents further wear of the regulator assembly, and retains mirror folding function when correctly installed. Compatible with common service procedures and straightforward to install for experienced technicians.
How To Replace
Replacement is typically performed from inside the door panel. General steps: remove interior door trim and water shield, support the glass in the service position (using tape or a suction holder), disconnect the electrical connector, unbolt the motor from the regulator, and install the new motor in the same orientation. Reconnect the connector, test the window operation before final reassembly, and secure the door trim. Check and lubricate regulator tracks and contact points during reassembly to extend service life.
Installation Recommendations
- Park the vehicle on a flat surface and set the ignition to accessory or battery disconnected state as appropriate for safety.
- Support the window glass before removing the motor to prevent glass from dropping and damaging the regulator or glass.
- Inspect electrical connector and wiring for corrosion or damage; clean contacts if necessary and ensure secure connection.
- Lubricate regulator tracks and pivot points with suitable grease to reduce friction and prolong motor life.
- After fitment, cycle the window several times and check for smooth operation and correct mirror folding function.
