1991 pontiac firebird dash lights went out

have you tried replacing the neutral safety switch located on the transmission?

All the lights stopping at the same time is not likely a fuse, it would be the brake light switch, the brake light switch is over the brake pedal near top of brake pedal arm under the dash. To test take a 12 volt test light ($5.00 at any auto parts store) and see if both side of the switch light the test light when the brake pedal is pushed, one side is hot with 12 volts without pushing the brake pedal down. The fuse location is in the owners manual but I am 99% sure that isn't the problem.

Check the brake light switch on the brake pedal up under the dash,it is most likely the problem.

FIRST CHECK AND SEE IF YOU HAVE POWER TO THE BRAKE LIGHT SWITCH ,IF IT DOES MASH THE BRAKE PEDAL AND SEE IF BOTH WIRES HAVE POWER WITH IT MASHED DOWN IF NOT THE BRAKE LIGHT SWITCH IS BAD ,BUT IF IT DOES HAVE POWER ON BOTH SIDES WITH IT MASHED ,BUT IF YOU DO NOT HAVE POWER TO THE BRAKE LIGHT SWITCH AT ALL CHECK THE BRAKE LIGHT FUSE IN THE FUSE BOX ,THEN CHECK YOUR TIL LIGHT BULBS NEXT ,IF IT IS NOT ONE OF THE OTHERS.

Check the brake light switch, it's under the dash near the top and on the back side of the brake pedal, press brake pedal down and see if that button pops out, if it doesn't tap on it, it should pop, if it does pop out and you still don't have lights, the switch is bad.

Look above your brake pedal and you will see your brake switch up along your brake pedal arm. It will either be between the brake arm and the firewall so when you brake it pushes the switch in. Or it will be between the dash and the brake arm so when you brake it pulls the switch out. Most likely this switch needs to be replaced

i would replace the brake switch it is located on a small bracket attached to the brake pedal ounder the dash

check dimmer switch for power if none then check lite switch!!!!

first of all the brake lights are always in the rear only!!. take the light bulb out and while some one is appling the brake pedal check to see if yo have power at only one terminal of the socket, then release the brake pedal and make sure yu dont have power at the same terminal , now if you had poer in one of the terminal then you have to replace the socket for the brake light bulbs.

look under the dash board right at the brake pedal switc where the brake light switch is located and make sure that the wires are not broken, you can also do a quick check by just disconnecting the brake light seitch and then jump the terminal off of the brake switch and you should have light if the light works this way then you have to replace the brake light seitch

you need to check the brake light switch, which is located under the dash, just above the brake pedal rod.. when you step on the brake pedal there is a spring loaded switch just above it that is allowed to expand, thus making an electrical connection and energizing the brake lights.
