Detailed Description

Compatible With 2008-2013 Nissan Altima, front left, w/ Auto-up, and 2009-2014 Nissan Maxima, front right, w/ Auto-up. This window motor is intended for vehicles that need a replacement motor to restore powered glass movement when the original unit slows down, stops responding, or operates inconsistently. The fitment coverage includes Nissan Altima and Nissan Maxima applications, and part number 388640 should be matched to the vehicle’s original configuration before ordering.

What It Is Used For

• Restoring a window that no longer moves with the switch
• Addressing slow, weak, or intermittent window operation
• Replacing a worn motor in an auto-up equipped window system
• Correcting noise or binding caused by motor wear

Installation Notes and Tips

Verify the original motor style, door position, and auto-up feature before installation. Compare the existing unit to part number 388640 to confirm the connector and mounting arrangement match the vehicle’s original setup. For best results, inspect the regulator and window tracks during service so the replacement motor is not installed into a binding assembly.
