    Brake Light Issue Fix

    Had an issue with my brakelights, and Luke gave a bunch of instructions in various posts, so I went through them, edited them into one post for clarity:

    Use CRC brand electrical contact cleaner.

    Clean all the plugs that attach all wiring. The third brake light, both taillight housings and the diode board.

    Third brake light
    Clean the bulb and the contact. Replacing it with a brass base bulb may help.

    Tail Lights
    Remove both the taillight assembly backings.

    Find the ground point, where a little wire connects all of the bulbs to ground. Take it off and clean it with CRC. Use a pencil eraser if it is really bad.

    Clean the connections to the tail light backing panel, and the bulbs/sockets. Make sure the ground wire is not corroded.

    Check relay/Diode board

    Remove the left trunk liner. In front of the antenna, find and remove the 2 screws that hold the diode board. It is a small black box, about 3" X 2" X 4" with 2 plugs. It is also called the Rear Lights Check Relay Diode board, and controls the taillights. Remove the box and clean the contacts with CRC.

    Connectors in Car

    Pull the back seat and clean the ground point on the left.

    Check to make sure every single connection is nice and tight. You can use a metal pick tool to pull the connections tighter.

    Check the brake switch, located under the dashboard, on the brake pedal assembly. If you are having a "ghost failure" issue, replace the bulbs first, then the switch...even if the bulbs are working fine.

    You forgot to mention that if all fails then just remove the damn bulb from the instrument cluster and tape the overhead check panel.
