My 2000 Plymouth Voyager right turn signal won't work, i changed bulbs and it still didn't work, the brake and reverse lights work with those same bulbs

Connectors in the socket might be at fault. Hold the bulb to one side and the other to verify.

As someone who has had fun with a right rear light panel on a toyota corolla I can sympathize. I went in to the shop and the guy replaced 3 bulbs on mine. Did yo fix the left signal light yet?

Some vehicles use a double filament bulb, if one of the filaments is 'burnt' out then the turn signal would work but the running/brake light would not work.

back to the brake light switch, power goes from the switch to the signal switch then to the taillights, the center light works on a different switch

Maybe a relay or fuse is bad or the wiring to it.

But you said that the third brake light works.

So the brake switch must be ok.
Turn signals would be the flasher or wiring to it.
CIRCUIT PROTECTION Fuse Block Fig. 1: The fuse box is located under a cover at the lower left instrument panel — 1987 Voyager shown
The fuse block and relay bank is located on the driver's side under the lower instrument panel. The fuse block contains fuses for various circuits as well as circuit breakers, horn relay, ignition lamp thermal time delay, and the turn signal flasher. The hazard warning flasher is mounted into a bracket below the fuse block. The individual fuse and relay locations can be found in the wiring diagrams at the end of this section.
is bad.

The first thing to check is the brake switch(es) that are on the brake pedal lever, and the circuit for the third brake light is seperate from the normal brake lights.

If the brake light switch(es) and wiring do check out alright then the problem will most likely be in the turn-signal switch, and the brake lights are ran through the turn-signal switch.

Hello. The symptoms you are describing are likely due to a poor ground. Temporarily install a new ground wire by securing a piece of copper wire to the frame with a self tapping screw. Use this ground wire along with the hot wire to see if each of these lights works. If it does, trace the ground wire back to the frame, unscrew it and clean up the metal with emery cloth so you reestablish a good ground.

the back bulb is out, replace it.

Your earth is bonding properly. Make sure you have a good bond that is fixed either to your chassis, with all rust, sealent and other cotings are removed frois should dolve your problem.m the fixing. Th
