    Only my center brake light works. The 2 outside lights don't work even after replacing the lights and fuses.

    I have the same problem. I have changed both brake light bulbs and checked all of the fuses under the dash and under the hood with no problems. I'm stumped on this one.

    My problem is the same with my 2001 Alero! We cannot figure it out at all. The fuses are all good as are the bulbs. Ours went out one by one and then sometimes they would work and sometimes not. Then the back window brake light went out and the only one working was the trunk lid light. Then this one began going out, dot by dot. Some days it would work completely and some days not at all. Now it is completely gone and I have no brake lights at all. When it was still under warranty we had electrical trouble with the turn signals off and on. They are not a problem anymore but what do we do about the dang brake lights? Someone suggested it might be the electrical harness of the car. HELP!

Check behind the brake peadle for a little button that pushes in and out when the peadle is pressed(this is your brake light switch) some cars have more than one of theese. manualy let the button out if the light works the switch is good if it does not disconect the harness from the switch and take a small piece of wire and jump the two prongs on the harness if the brake lights come on then you need a brake light switch. if this doesnt work check for power at the switch. if no power you have a bad fuse if there is power and you already jumped the wires to the switch then you have a broken wire between the switch and the tail lights.

My 2001 Alero I just replaced my tail bulb in the rear. THe following day ALL my rear lights work however when I brake the brake lights in the rear do not engage. I Checked the fuse (fine), removed the bulb I replaced (Brake lights still did not work), I don't think it is the electrical because the lights themselves work. COULD IT BE THE BRAKE SWITCH??? that would be the only relevant option however I do not want to pay $150 to get it diagnosed

Check your fuses and both bulbs. I have seen 2 bulbs go at the same time.

1998 chevy lumina: rear window brake light not working, left brake light not working, rear left turn signal not working


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.

Brake light, reverse light and turn signal issues


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.

1990 Volvo DL Sedan Brake Lites Work but Also Come on With Running Lites


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.
