Default Brake light issue NEED HELP!!

Few weeks ago I noticed all my brake lights were lit up on my 05 Bonneville when the car is running and turned to the on position. I checked the switches on the brake pedal and replaced them anyway but the lights are still lit up. Any ideas on what it could be?

Thanks!

There might be a short some where. Start with the brake trigger switch.

Is that located under the hood or by the pedal? This problem is completely new to me

Yup its under the pedal, but I believe you have replaced it right? Just make sure that the connecting wires aren't crimped or splice that could be touching the body ground.

I just got under there and looked. All the wires are good and have tubing all the way from about half inch behind connectors.

So, if the car is not running, the brake lights are not on?

If they are on, do they go out when you disconnect the brake switch?

Yes, the brake lights are always on except when car is off. When the brake light switch is disconnected they are still on.

Any aftermarket accessories installed?

With the brake switch disconnected, those brake lights should not be on....

Power to the brake switch is constant.....so if the key is out of the ignition, and the brake lights are off, and you step on the brake pedal and they come on, the circuit and switch are ok......

So either, there is an aftermarket problem, or somehow the circuit out of the brake switch is shorted to voltage.....

What you can try, with the brake switch disconnected, pull fuses one at a time, and see when the lights go out, and this will point you in the direction of the circuit that is causing the problem....
