This procedure concerns both front and rear doors. Starting from pulling the cable out of negative terminal of the battery, in models which have options of power windows as well as the door locks. Then, pop the screws from the door trim panel and water-shield out of the car. Then, remove the internal trim piece and then the door glass. Disconnect its electrical connector which supplies power to the motor for the power window, then remove the retaining bolts, and require to slacken one bolt to allow the window regulator to be raised and the regulator can then be pushed out through the access hole. In case of the body power window models, disconnect the fasteners of the power window motor and detach it from the regulator for the sector gear to be fixed into the regulator web before you unlock and disconnect the mounting fasteners. Removal is done in the reverse order with attention to the fact that all regulator rollers should be lubricated with multi-purpose grease, all bolts tightened and that the bolts of the rear doors regulator, should be tightened in criss-cross fashion.
