Driver side tail light won't work - 1998 Plymouth Breeze

The tail light assembly contains the circuit boards on each side. Driver side and passenger side each have their own circuit boards when you remove the tail light assembly.

You have a short in the cross over wire. Almost all cars and trucks have one main break wire with a second wire "y" in off to the passenger side . You could just wire in a cross over and disconnect the old one.

Start by replacing the light bulb.

those lamps have 2 filaments and one of them (the lower brightness one) is burnt out and the brighter one (brakes and blinker) still works. you need to replace that lamp

pull your brake light assmb out and check your connections including ground

You don't really need a diagram, it's simple. If you open both tail light boxes in the trunk you will see at the connector on the bottom a yellow wire in the first position. That goes to the brake bulb. If both tail lights do not work, make sure you are getting power to the driver side light first, if it is not getting power, the passenger side will not work either, they are in line with each other. If it is only the passenger side not working, the bridging wire could be bad.. try jumping it. Also, make sure you are getting power inside the tail light bulb holder. The metal connections can come loose. If there is no power to the driver side tail light it could be the bulb failure relay, that is the round red relay in the rear left side of the fuse box behind the ash tray/ cigarette lighter below the radio in front of the shifter. You should be getting power to the third brake light in the rear window...that is a different circuit and will not be affected. Try changing out the bulb failure relay, it supplies the power to the tail lights.

Sounds like you need to replace the drivers brake/tail light.

Bad earth connection.Clean or replce wire.

bad ground or possible a bad tail curcit board.

I hope you arent letting a simple thing like a burnt bulb ruin your day??Im not sure what you have checked so far but start with replacing the bulb,check the connector very good as this has been an issue on many makes and models
