Center Brake Light Not Working

Ok, trailer lights are basically separate circuits from the regular stop lights and same with the center brake light.

There is a brake light fuse located in the fusebox next to the battery in the engine compartment. Use a 12v test light to see if it becomes hot both sides of the fuse, when the brake is depressed.

12v Test lights can be bought at a auto parts store for less than $15. Do not get a "continuity light" as these are different. A test light, lights when you touch a terminal and voltage is present using the alligator clip attached to a good ground

Notice that the center stop light does not go through this fuse in the diagram.

I have included a wiring diagram for your vehicle.







If you find the brake light fuse blown, and it repeatedly blows, you have a short to ground from the fuse to the brake lights somewhere. First step is to check the brake lights for a short. and work your way back to the fuse.

The first step is to check the bulbs in the tail lights. The brake light switch (on the brake pedal) is OK, as the center light works.

If the hight mount brake light is working , then your switches , fuses , relays , are OK . Most likely problem is that the bulbs themselves are burnt out , or there is a broken or loose wire.

See if bulbs have burnt out in the left brake light and rear turn signal (one bulb if combined) and also rear center high mount brake light.

If the left turn signal has a slower speed than the right turn signal, this is a symptom of a bulb or bulbs burnt out.

Usually, the wiring is not a problem, but I would not rule wiring (or sockets) as a problem out.

Good luck on this repair.

bulbs might look o.k. & still be blown, trust me get new bulbs anyway.

LH/RH lights cable could be disconnected anywhere, will take a long time to trace.
Center Brake Light and LH & RH should be connected at one point.
Jump a cable from Center Brake Light to one of Rear Break Light.
Hope this will works.

Is the top center light working (the light at the window)?? If not, check your brake light switch at the brake pedal. It may be damaged or needs adjustment. If the center light is still working, you will need to have the ground and leads checked at the brake lights. Hopefully this helps

Check the connection at the brake light switch for power comming out to the barke lights,try feeding power to the brake lights manualy using a jumper wire from your fuse box or battery,unplug the wire from the switch and put power to the harness if everything is OK the brake lights will work,then you need a new switch.

Is there a switch on the left side of the dash that has a red lens and a wavy line across it? If so, you have a rear fog light switch and it has been activated, causing your brake lights to come on each time you turn your headlights on. Flip the switch and the rear lights should display only the parking lights with the headlights on.

Do you know if the brake light bulbs are working? (are the bulbs good?). (the bulbs have two parts, one for brake lights the other for running lights)
If the third brake light bulb is working the brake lights should be with good light bulbs.
