Open the hood and, using an insulated wrench, separate the negative battery cable remote terminal from the remote battery post. To remove the master switch, place the special trim tool C-4755 beneath its bezel and pry it up, then lift out the bezel and disconnect the wire from the back of the switch before pulling the switch out. Before switching, open the door trim panel, disconnect the switch's wire and remove the switch part from the vehicle and its bezel. Start by opening the rear door and pushing slightly up on the rear side of the switch while also pushing toward the switch opening. Then pull the whole switch up and out of its place. Pull each tab on the side of the switch connector, then pull the connector out of the switch. Then, carefully lift the switch from the vehicle. For installation, join the wire connector with the master switch, place the switch on the trim panel and put back the negative battery cable at the remote terminal. Attach the switch and connector for the passenger door, add the door panel, then hook up the negative battery cable remote terminal and the door trim once again. To set up the rear door switches, fit the connector to the switch, set it into the door trim panel and attach the negative battery cable remote terminal back.
