Just bought the truck. Rear lights don't work.99Chevy Silverado

Bad wiring to the rear tail light cluster.

if there is a tow option on that truck check the wiring on the socket for the trailer.and where thy tie in to the rear lites sometimes ther is a short.hope this helps.lucas

Check the harness connection for trailer hitch lights near back bumper in chassis rail. launching a boat gets this connector corroded.

most blinkers uses relays, and when they flashes fast one light is out, but you replaced your burnt bulb might be a bad relay.

yes, on multiple electrical problems like this the first thing is to check the ground circuits, in you case focus on the left rear

I've worked on these the first drove me crazy. its the turn signal switch every thing runs thru these. head lights, turn signal, brakes. except the third brake light. it runs directly from the brake switch. go figuare

I have the exact same problem with a Ford Escort. Anybody have an answer?

If the driver's side tail light is working, it's not a fuse. Use a test light to check for power at the bulb holder. One terminal will be for tail light, the other for brake/turn light. If the is constant power for tail light, replace bulb. If no power, trace wiring from bulb holder to driver's side junction. Probable broken wire between the two tail lights.

the blinker is behind o next to the brake pedalit coul be the problem brake ligth swich is ataached to bhe brake pedalhold by two screws o pins first check for groud o positive
