Is the front left (driver side) window on your Infiniti QX60 or JX35 stuck, slow, or making grinding noises? This power window regulator is a direct replacement for part number 807213JA0A, fitting 2004-2020 models. It's brand new, unbranded but built to OEM specs, and comes with a 1-year warranty. Note that the motor is NOT included – you'll reuse your existing motor, so this is perfect if your regulator is broken but the motor still works. The regulator includes the metal and plastic mechanism that moves the window up and down. Installation involves removing the door panel, disconnecting the old regulator, and installing this one. It's a common repair that DIYers with basic tools can tackle, saving you hundreds in shop fees. Get your window rolling smoothly again and restore convenience and safety. A reliable fix for a frequent issue in these SUVs.
