    Q:
    How to remove a window regulator assembly from a door? Posted by Customer
    A:
    To remove the window regulator assembly from a door, first remove the door trim panel and water shield, followed by the door window glass. If equipped, remove the large door trim bracket covering the door opening. The window regulator assembly consists of two guides and cables, and can be removed by pushing the guides toward each other to collapse the assembly for easier removal. For access-type rear doors on extended cab pick-up models, the regulator consists of one guide but removal is basically the same. On power window-equipped models, unplug the electrical connector for the regulator motor before removing the regulator from the door. To install, simply reverse the removal process.
