Chevy 35000 right side marker lights are out but left side works
Are the marker lights set up on separate fuses for
each side
Note the diagram, side maker lamp, toward bottom of diagram. If the tail light on that side works, the problem isn't a fuse. In diagram for side marker lamp, that top wire is voltage, bottom wire is ground. You can see wire colors, you can check voltage and ground with a test light. Is the bulb good? good luck
