How to Replace the Center Tail Light on a 2003 Cadillac CTS

The 2003 Cadillac CTS features three brake lights, as do all modern vehicles. The "neon" third brake light sits on the vehicles trunk lid and not in the back window bay as is common in many other cars. If you want to install the light yourself, it should only take a few moments. If you have not worked with taking apart any pieces of a cars body, however, you may want to let a professional take care of the replacement.

Instructions

    1

    Remove the cover that surrounds the license plate area and runs along the bottom of the light assembly. Use a small flat head screwdriver to start the removal, taking care to not scratch the paint on the cover.

    2

    Use the screwdriver to pop the light assembly out of its retaining clips. Be especially caul when loosening the light assembly, since it can crack if you apply too much force.

    3

    Press on the clip on the light assemblys plug that is joined with the wiring harness inside the trunk. Place the old light assembly to the side on a soft cloth.

    4

    Insert the plug on the new light assembly into the socket in the wiring harness. Line the tabs on the back of the light assembly with the retaining clips on the trunk lid.

    5

    Press the light assembly into place gently, listening for the retaining clips to snap. Make sure the light assembly does not jiggle at all; otherwise, remove it and install it again.

    6

    Press the cover that goes around the license plate area and underneath the light assembly back into place so its retaining clips snap into place. Make sure the cover does not jiggle when you press on it.
