93 Cutlass Supreme brake light

I have a 93 Cutlass Supreme, The drivers side brake light does not work. The drivers turn signal light works, but not the brake. the pass. side brake light works. All the bulbs are good. I have checked the connections and they are good. Any help would be greatly apreciated

Your lower brake lites and turn signals use the same bulb filament, just not at the same time. The lower brake lites are wired through the turn signal switch. If no voltage when there should be, check at the turn switch.
