Tail lights

Asked by Howec92 Feb 03, 2019 at 03:06 PM about the 2003 Chevrolet S-10 LS Extended Cab RWD

Question type: Maintenance & Repair

My tail lights don't work. Brake and turn signal do but not the night time running
lights no matter what position the headlight switch is in. The headlights and
running lights on the front always work and can't be turned off.

Note the diagram, sometimes they call the tail lamps--park lamps, You can see the two fuses, rr and lr park lamps, Use a test light and check voltage on those fuses, the fuses go hot when the park lamp relay is energized. At the rear tail lamps, brown wire is voltage and black wire is ground, check them both.
