Under the left side of the dash
Parking lamps fuse is under the hood at the fuse box located by battery, but the brake lamps are located at the side of the dashboard on the passenger side, you will see an oval shape cut out when you open the passenger door, pull/pop that panel off with a flat screwdriver, the label for fuses will be on the inside of that panel. If your small brake light in the rear window is working, and the tail lens lights aren't, this is a sign of a bad combination switch which is what you move to select turn signals or activate "brights."
VERY CAREFULLY
I believe most brake light switches are located under the dash above the brake pedal.
I have a 1992 regal and it is located under the glove-box behind a piece of black plastic.
The 2001 Buick Century brake light switch is located beneath the dashboard, on the drivers side. The brake light switch should be labeled as such.

Check your Brake fluid. If the fluid is low then will make the Brake light go on. anothe thing is you might be needing new brakes soon..
how do you change the rear license plate light on a 1999 Buick Regal
There is a problem with the Anti-Lock brake system. Seek professional help.
the brake light fuse is located where the brake pedal is at... just take the cover that it has above the brake pedal and you're gonna see fuses on your left....
Should be a screw on either side - remove and cover should lift off
Most likely it is either the brake light switch, under the dashboard, connected to the brake pedal or the turn signal switch inside the steering column.
The check engine light on a Buick Regal can be reset with a special diagnostic scanner. This can be performed at a car dealership or service garage.
