Once and a while they will finally kick in and start working again.
2004 gmc sierra tail lights not working.
Burnt out light bulbs the other reason your tail lights are not working but your headlights are maybe a blown bulb.
On the 2004 silverado sierra the fuse for the trailer running lights is in the fuse box under the hood not in the passenger compartment like the fuses for the right turn brake and left turn brake.
I have changed the bulbs fuses checked the tail light circut board checked the headlight switch.
It is not a primary vehicle weekend warrior project vehicle but at 257k miles and not burning or leaking any fluids she s worth the continued support.
Noticing that some lights were not working thought the bulbs were burned out.
When the filament inside the bulb breaks it cannot illuminate the gas enclosed within the glass cover.

I recently noticed i don t have any brake lights none of the 3 are working.
Electrical is not my strong point so any help would be.
When i checked the wires at the tail light only the wire that worked the turn signals had juice the other 3 did not.

If the tester lights up your fuse is functioning fine.
If it does not light up then replace the fuse with another of the similar amperage and size.
I replaced all the brake and trailer related fuses and replaced the brake switch on the pedal and still nothing.

Recently been having issues with the rear taillight assembly.
The brake lights turn signals reverse lights all work but the tail lights when you head lights are on do not work.
In many instances you can see the break in the metal strip of the fuse.
I own a 2004 chevy silverado 1500 v8 5 3l with factory installed 5k 12k tow package.
I decided to replace them with led bulbs.
The brake lights turn signals reverse lights all work but the tail lights when you head lights are on do not work.
Replace the fuse but before plugging the trailer back in you need to search for a short circuit on the trailer that could cause the fuse to blow.
Instrument lights not working when dash lights don t work odds are the tail lights don t work either sounds like dimmer switch may be a problem.
