Begin the service or repair of a front door window regulator by removing the panel on the door trim. Then, take the glass out of the regulator roller track and settle it inside the door at the top. Unplug the power
Window Motor at the connector and remove the screw that keeps the regulator scissor channel in place on the door panel. Remove the heads of the screws and bolts from the keyhole openings in the door panel, then loosen the bolts holding the regulator to the door panel. For JR-27 (Convertible) models, take off the water shield, cut the wire linking the power window motor and remove the regulator lift channel nuts, keeping the glass near the top. Put a mark where the rear bolt of the roller channel is on the inner door panel, then separate the rear bolt from the door panel and loosen the front bolt. With the door panel open, take out the roller channel and release the bolts at the attachment point of the window regulator. With the regulator free, fit through the large inner door opening and remove the motor from the window regulator. Install the regulator by lowering it into the door from above, passing it through the access hole and seating it by tightening the bolts. Line up the screw and the bolt at the keyhole, insert the screw into the regulator scissor channel slot and tighten it. Fit the glass into the roller channel, rejoin the power window motor wires, tighten all the fasteners and install the trim panel. With the JR-27 models, fit the power window motor to the regulator, set the regulator in the door assembly, slip the bolt heads into the door's keyhole slots and tighten everything with the bolts. Adhere the roller channel to the door panel with the rear bolt positioned as you marked it, tighten both bolts, secure the regulator lift channel and install each nut. Test the glass movement once you are sure it matches properly, making required adjustments and then attach the wire connector to the power window motor and put back the door water dam and trim panel.
