Sounds like you lost a ground on your turn lamps
did you just connect a trailer or something
if so go back and check your connections

1998 monte carlo brake lights dont come on


This is fairly easy to diagnose. Down by the brake pedal there is a switch. You may have to remove some trim panels to access it. There should be one wire with power all the time. There should be another wire that has power only when the brake pedal is depressed. If there is no power on any of the other wires with the brake pedal depressed than the switch is bad.

If there is power than the more common problem is the turn signal switch. I know it doesn't sound like it could be the problem but let me explain how it works. the turn signal and the brake use the same bulb. In order for the correct power source, brake lights or turn signals, to get to the correct bulb the turn signal switch is used. If you are not turning the power from the brake switch is routed through the turn signal switch and then sent to the two brake brake bulbs. If you are turning to the right power from the brake switch is cancelled to the right bulb and replaced by power from the turn signal flasher.

One quick way is to see if the third brake light is working. If it is you know the brake switch is working since power to the third brake light bypasses the turn signal switch.

Good Luck and let me know how it goes!

Lumina troubleshooting


Check fuse.
Check if center light works.
Check for power at light sockets.
Check brake light switch.
Manipulate the turn signal lever.


- To check the brake light fuse, open the passenger door and remove the fuse panel cover that is located around the corner from the glove compartment. On the back side of the fuse panel cover there should be a fuse location chart. The brake light fuse is #23, located in the socket that is dead-center among the mini fuses. I believe it is supposed to be a 15A fuse. Confirm the condition of the brake light fuse and replace if necessary. If the fuse fails again, determine and correct the cause.
- Also, see if the center brake light is working properly. If it is, then the brake light switch is working. If the center light is not working, the brake light switch is suspect. That switch is a spring-loaded plunger switch that is of the "normally closed" variety. In this application the switch is usually held open by the brake pedal arm, except when he pedal is depressed. Then the spring within the switch holds the contacts closed so that the brake lights will operate.
That switch is located under the instrument panel. Look for a push-button switch that is contacting the brake pedal lever. If the car has cruise control there will be two switches, one above the other. I believe that the lower of the two is the brake light switch.
- With the brake pedal depressed, see if you have power and ground at the brake light sockets. One good way to confirm that is to remove a brake light bulb and connect a 12v. test light across the contacts in the socket.
- An operating center brake light combined with no power to the 12v+ terminals at the left and right brake light sockets could indicate a defect within the turn signal switch. If you get to the point where you suspect a defect there, try applying rearward pressure on the turn signal lever and see if the brake lights work then. If that procedure confirms that the defect is within the turn signal switch, you can replace the turn signal switch. Or you could try my trick which cost me less than a dollar and has worked for years.
See attached photo.

Spacer (piece of rubber tubing?) is used to apply rearward pressure on turn signal lever. I have not disassembled the switch assembly, but evidence suggests that electrical contacts inside the switch depend on the mechanism being positioned properly. If the internal positioning device failed (perhaps the lever was pushed forward) then an external device can be made to hold the lever and switches in proper location.
If you attempt this repair, consider applying some lubricant as deemed necessary.
Good luck.

98 chevy lumina Rear window break light works, but rear break lights don't, also right turn don't work?


I can almost 100% guaranty the turn signal switch is the problem. Power for the brake lights starts at the brake switch. power then splits from there and the third brake light gets power directly from the brake switch. Since the turn signal and the brake lights are on the same bulb power for the brake lights is routed through the turn signal switch. the switch depending on what position it is in will allow brake power or turn signal power to there respective left or right brake/turn bulbs.

If you hold your foot on the brake pedal and wiggle the turn signal and or play with the hazard switch the brake lights will almost always intermittently start to work. this will confirm a bad turn signal switch which is pretty common on GM vehicle with this style setup.

Hi: I have a 1998 Chevy Blazer 4.3 The brake lights and turn signals don't work.... HELP


Sounds like you have a bad multiple function turn signal switch. A couple things to try With your foot pressing on the brake pedal, Press the four way flasher button up and down, press and hold it down, pull up on it, or wiggle it. If the brake lights come on during any one of those replace the switch. With the key in the run position pull, push, the turn signal lever slightly. If the turn signal or brake lights start to work replace the switch. Let me know if none of those work, they usually do, and I'll get you some more in depth diagnostic info.

I have a Chevy 2500 4X4 with brake lights not working. I have all other lights working. I only have one brake light working when I turn on the right turn signal then my left brake light will work. What's...


What year?

Sounds like a turn signal switch. Earlier models would use the same bulb for the brake and turn signal. The turn signal switch will interrupt power to the brake light and route the signal to either the left or right bulb depending on with way you where turning. Usually you can wiggle the turn signal switch and get the brake light to work momentarily when this is the problem.

Newer vehicles use a lighting module that looks for inputs from the turn signal switch and brake pedal switch and then decides where to send power. This module is also know to go bad.

Sounds like maybe a bad turn signal switch. If the brake and turn signal use the same bulb than the turn signal switch will interrupt the brake signal and supply a turn signal to the bulb. Usually you can wiggle the switch while holding the brake pedal down and get them to intermittently work. If that happens than for sure the switch has failed.

Have a 96 Olds Cutlass Supreme, brake lights will not work. We've replaced bulbs, fuses and brake light switch and still nothing. Help!


Try having someone push on brake pedal at the same time thay move the turn signal lever up and down slightly to see if your brake lights work this would tell me that you have a faulty turn signal switch because GM runs the brake lights thru the turn signal switch so they work if you are driving with your 4way flashers on.

No brake lights when i push the pedal


Its the signal light switch on the lever.
THe signal switch has all connections relating to the brake lights!
solution play around with the lever and see or get someone to see the brake lights work with the brake pedal down.
My car does the same thing! when i move the lever towards activaiting the high beams the brake lights work.
just gently push on the lever to see the lights go on.
you have to replace the switch and requires removing the steering wheel without setting off the airbag.
