Here it is

Get a wiring diagram from the Free portion of the Autozone site. It is a little work to separate the Help categories at the bottom of their Webpage.

I have heard of SOME 4-way flashers that are built into the turn stalks causing problems. The contact pins for the turn signals are shared as 4-way flasher pins. Try clicking the 4-way flashers off/on about 20 times and then use the left turn signal. It has been known to reseat the contact pins.

The wiring diagram I mentioned would show where the tailgate top light gets its power. One feed should go to the brake light switch for the brakes and another feed should be the flasher feed.

As I see it, you have 2 extra lights going on when you use the left turn signal. Those 2 lights are the tailgate light and right turn signal. The wiring diagram should show the places where the wires are close enough to cross. I am thinking the 4-way flasher is the only place where the top tailgate light gets flasher power; the rest of the time the tailgate light is a Brake light.

I do not want to spend your money on an unnecessary turnstalk and that is why I say to look at a wiring diagram and see if there is anyplace where the wires could cross.

Last, trailer hitch plug. All wires are bundled with left turn, right turn, and brake light in the trailer hitch plug. Corrosion could connect the terminals.

Would like to know what you found.

This may sound confusing, so here goes.
Normally I would say check the turn signal switch because for decades the brake light switch power went thru the turn signal switch.
But in your case, its more complicated.
The wiring diagram looks like you have a wire from the brake switch and another from the turn signal that joins inside the right and left rear tail lamp assembly. There are also fuses in the rear fuse box including one for just the brake lights. So its possible that fuse is dead and yet the turn signals would work.
You may have to get a book with the wiring diagrams to trace the circuits.

Turn signal tail lights and BRAKE LIGHTS NOT WORKING

It can be faulty brake light switch causing the problem or its blown brake light bulb. First check and confirm brake light lamp is working and that's not the case.

For turn signal not working it can be faulty turn signal switch or its issue with wiring:----

These will help.

Thanks.

here is a wiring diagram. Are the bulbs for sure good?


hope you can read it.

If the third brake light works and the regular ones don't, it is most likely a bad turn signal (multifunction) switch. The switch is able to kill the brakes lights to run the turn signals, and in rare circumstances does this. I've seen it several times. It could also be wiring, especially near the turn signal switch, but it is usually the switch.

why not just replace the turn signal switch must faster and safer . buy one from your local parts house then you can see its not that easy to install but you can do it with a little help
