Hi

this may be because of the following reasons.

1.there wil a junction box/relay which connects bake light and turn signal may be damaged or connections from this may be disconnected.check it.
2.the wire connecting this relay may be damaged so no power going to the junction box/relay.
3.wire from the battery terminal disconnected

uf you feel my answer was useful please rate me

Usually this indicates that the brake light switch or turn signal or flasher have failed.i would start by replacing the brake light switch located on the upper area of brake pedal and fix ya problem.

Tail lights don't work on 83 cutlass supreme

I assume you checked the bulbs and they were good? It's possible that the sockets have gone bad and need replacing. The tail lights are fused through the instrument panel lights. that fuse should be in the middle of your fuse box, marked "instr". If the fuse is good check to see if the dash lights come on when you turn the headlight switch on. If they don't then change the headlight switch. hope this helps.

The brake lights do not, however the 3rd brake light turn signals work

check brake lights relay--probably in engine compartment fuse box.

Please see my tip at http://www.fixya.com/cars/r6053280-lights_out_lights_not_out_bulbs_ok and let me know if you have questions.

Have a 96 Olds Cutlass Supreme, brake lights will not work. We've replaced bulbs, fuses and brake light switch and still nothing. Help!

Try having someone push on brake pedal at the same time thay move the turn signal lever up and down slightly to see if your brake lights work this would tell me that you have a faulty turn signal switch because GM runs the brake lights thru the turn signal switch so they work if you are driving with your 4way flashers on.
