Remove the door trim panel, watershield, and radio speaker. Next, take out the window glass. Disconnect the window motor's electrical connector, if equipped. The regulator bolts fit into slots in the door; loosen the two regulator bolts at the slotted holes without removing them, then remove the remaining regulator mounting fasteners. Slide the regulator until the loosened bolts clear the slots, tilt it toward the front of the door, and lift it out. For installation, follow the reverse process of removal. The removal and installation of rear window regulators are similar to the front doors, with differences in the location and number of mounting bolts.
