On my 2003 Chevy silverado both rear turn signals don't work. The bulbs are fine and the fuses are good. Can't figure it out

SOURCE: No rear brake light / turn signals on 2001 Chevy Cavalier

The problem is the turn signal/headlight/hazard switch assembly on the steering column which the brake light wiring runs through. The part is easy to change and cost about $50 at most parts stores

SOURCE: no turn signals or side brake lights on 94 chevy suburban

the problen is probably the turn signal switch with a test light check for power at brake switch if no power check for power at turn signal switch the brake lights are incorperated through the turn signal switch

I have a 2002 Chev Cavalier that had the same exact problem. I replaced the bulb harness (purchased from a chevy dealership for around $5) which was fairly easy to do. I have had zero problems with it since.

check the wiring from the tailights back to the fuse panel, it sounds like an open connection. if i recall correctly check under the dash on the drivers side near the fuse panel for a bunch of wires in a bundle and look carefully for a wire or two that are cut/shorted/or seperated, you can also check under the drivers side kick panel by the hood release.

check fuse under hood, batery terminals coroded wire at harness if everything fails run a hot wire to rear brake line with an interuptor.
check the swich under the foot brake.
