Why wont brake lights work on a 94 CUTLASS supreme?

Check bulbs - double filamented smaller is for stop lights and larger for tailights Check fuses

Check power to and operation of the stop light switch

Usually located at the upper end of the brake pedal under dash area

Don't know technical name but there is a multi-functional switch on your steering column that is tied in with the turn signal actuator. Whole unit is replaced as one. Parts house $350-400+. On line about $250+. I was told it would take about 1- 1 1/2 hours for a mechanic.
