2002 tahoe - 2 brake lights dont work. Cargo light does. Changed the brake light switch. Still no power to lower 2 brake lights. Bulbs and fuses are good.
Do your rear turn signals work? If so the wiring is intact from the turn signal switch (in the steering column) to the brake lights. Check for power going from the brake light switch to the turn signal switch. If all is ok there, turn signal switch is probably bad. Even if you're not using your turn signals power goes through the turn signal switch to the brake lights, just in case you do decide to signal a turn. HTH. -Jim
It could be a grounding issue. I would also check for a box not far from the tail lights that all the wires go into that may have some breaks in the wires. I have had to change out the box before because of loss of lights.
there is a circuit board with 2 or 3 plugs under the driverside in the rear of the vehical. plugs get corroded or the board just burn out. you may want to check there..
Where is rear fuse box located on 02,tahoe
