Right rear taillight not working - 2003 Chevrolet Silverado 1500

It could be the bulb even if it looks good. Could also be a loose wire or even the connection where the bulb is inserted into.

Tony, our TB's only have 3 bulbs, 1 brake, 1 running, 1 backup.
If you happened to be playing with NEW LED bulbs (from local retail location) for the brakes, guaranteed you blew the fuse under the rear seat. It takes a special CK socket for the brakes that no one carry's. If you're only dealing with normal incondecent bulbs, I'd still check the fuse under the rear passenger seat.

You obviously have a bad connection somewhere in the taillight. Some trucks it is a common problem and the taillight circuit board is the problem.

If after checking the bulbs are ok then the fuses could be suspect!

You could have pinched a wire. Check to see if there is power going to the bulb by using a test light.

what type of light? turn signal,taillight,or brake light. if the right rear isn't working but the left rear is on the the brake light or the taillight then the problem isn't the fuse(the share the same fuse). may want to check the bulb socket on the right rear. the contacts get hot and melt the socket and the housing.

Yes. But do you have seperate yellow turn signal lights in the rear or do the turn signals work independant of the brake lights? If yes then you need to wire in a taillight converter. It takes your seperate left & right turn signals combines them with your brake lights on 2 wires instead of 3 leaving you with your normal 4 wires in total instead of 5. 1 Left turn & brake light. 1 Right turn & brake. 1 Taillight. 1 Ground. = 4 wires in total. If you dont have seperate rear turn signals just find left turn wire in taillight assembly, Right turn wire & Taillight & a good ground & you are done. On trailer plug yellow is left, green is right ,brown is tailight & white is ground.

OPEN THE TAILGATE AND YOU WILL SEE TOO BOLTS OR SCREWS..UNDO THEM AND PULL ON THE ASSEMBLY AND IT WILL COME OUT....PRETTY SIMPLE THEY ARE PRESSED IN...

2002 Chevy Express Van>>>>with headlights off--the rear left taillight works, but no right. When the brakes are stepped on, both taillights don't work. Also, the little lights under the back doors are out. Also, some lights are dim>>rear only.
