| The first two steps
are to open the rear cargo liftgate and locate the small square tail light
bulb access panel. You can pry out the panel with your fingernails or use a
flathead screwdriver. The Brake Light bulb is located at the middle of the tail light assembly and is the only bulb socket connected by a wire harness. Remove the socket from the assembly by rotating it 1/4 turn counter clockwise before pulling it straight out. Pull the old # 7443 brake light bulb straight out from the socket and push in a new one. Insert the bulb into the tail light assembly and rotate the socket 1/4 turn clockwise to secure it in place. |
