First, one wire cannot control the turn signal and brake light, as the turn signal and brake light have to work independently of each other so I would verify the color code for the brake light wire and then check it.

I have 1991 Nissan maxima. All my lights,tail lights and brake lights work EXCEPT my left brake light. Changed the bulbs and still dont work. Can someone help?


Pull the bulb back out and look in the plug. They get corroded and the tabs will spread apart and/ or break off. Bend them back if they are there, replace it , if not.. If it looks good, you need to use an ohm meter and check continuity of the tabs to the wire. They usually break close to the plugs.

My left brake light/turn signal isn't working! I replaced the bulbs and turn signal flasher! Still not working! Its 2000 Chevy s10 blazer


If the other brake and turn lights are working the brake light and flasher units are ok . With a test light check at the bulb holder terminal and bulb holder body, test light should glow ,if not check from terminal to a metal part of panel away from the light body . If test light now glows the brake light body has a bad earth if the test still not glowing the power cable to the light is broken.

No brake lights on my 02 blazer, i have running, turn, and hazard lights. replaced brake switch and nothing still. theres a auto start system on the truck that came on it when bought used. its hacked in...


Check for 12 volts coming into the brake light switch. If you have that you should have 12 volts exiting the switch when the brake pedal is depressed. If you have that and the center brake light works you have a problem with the turn signal. If the center light doesn't work you probably have an open in the brake light circuit between the turn signal switch and light bulbs. If there is no voltage at the brakelight switch you have an open circuit before the switch. I'm assuming the fuse is good.

Brake lights don't work


This sounds like a bad brake light switch, this switch is located on the bracket that holds brake pedal,you can test for power at switch,also if you remove connector and jump terminals with a wire and see if lights lite, if lights light then switch is bad,

Left rear brake/running light not working


If this is a trailblazer check all the other bulbs in the rear you probably have more than one bad bulb. Chech the bulbs for slight blackaning (flash).

Brake lights not working but third brake light works?


Check your fuse for the brakes, if fuse is blown replace. If not fuse go buy a package of brake light bulbs at the auto store. Then replace the bulbs.

Hope this helps

Left rear brake light stopped working but bulb and fuses are OK.


These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!
