Installation Notes and Tips

This assembly uses a bolt-on attachment type and does not include mounting hardware or installation instructions. Verify front left fitment by year, make, model, and door position before installation, and inspect the window glass tracks and electrical connector condition during service. Because the gear material is plastic, handle the assembly carefully during installation to avoid damage to the drive components.
