How do you repair a window regulator on a 2003 Ford Expedition?

REMOVE THE DOOR PANEL once the door panel is off,disconnect the harness that is hooked to the power control switch, windows etc, after that you will see maybe 2-3 bolts on the door which holds the window regulator, unbolt those be careful of the window, you should have some screws that hold the glass to the regulator bracket, unscrew those to release the glass, you may want to use something to prop it up so it dont break, once you unbolt it slide the entire unit out, you will see the regulator and the motor, just unbolt the regulator and put the new one in and reverse the procedure.
