The most common cause would be a Low Brake Fluid situation in the Master Cylinder. Also, the ABS system has a balancing valve in the Fluid circuit. If the valve is not in the normal position for some reason, the ABS System should see this as a fault and turn on the light.
It's on top of the brake pedal under the dash.
you either have a blown bulb or you have a broken wire
It will, if it causes the fuel mixture to be out of range.
Most likely because of a problem with the ABS system, which could be expensive to fix. It could also be caused by low brake fluid.

where is the brake light switch for 1996 Oldsmobile cutlas supreme
Yes, My 72 Olds Cutlass convertible came with the light option package which included a map light in the rear view mirror.
There is no brake light relay. There is however a brake light switch located above the brake pedal.
Probably because you need to check the engine.
One of two things. Either the brake light switch behind the brake pedal. Or try wiggling or rotating your turn signal stalk in a circle motion. If the brake lights work when the turn signal stalk is wiggled then you need to replace the turn signal stalk.
