I have a 2001 S-10 that has turn lights but no brake or tail lights, but the light on the top of the cab works well. I have checked all fuses in the cab as well as under the hood but see no blown fuses. I have also checked all the wiring under the bumper and saw one ground not connected and was hoping that would be the resolve, but it wasnt. Does anyone have any suggestions?
Hello Dallas,
There is a possibility that both bulbs are burned out or the paste that GM seals the lamps sockets with is preventing a good connection between the contacts.
Remove the bulbs and test for power (with the brake pedal depressed or the running lights turned on.)
If your multi meter reads voltage, it's the lamps, if not...check for continuity on the brake light switch (connected wires removed.)
The headlight switch controls the running lights, the brake light switch controls the brake lights. Good grounds are also critical so make sure they have clean solid connections.

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 grounds on rear light assy's

The wire may have a break inside its insulation you may have to replace hole wire.
