on an 83 its either fuses,bad wiring or maybe even bulbs. oh yeah the sockets could be bad. one will cause the other to not work.

the bulbs have 2 filiments,one for brake one for tail light. check bulbs if they good your swich is bad

This is a common GM specific problem. Your turn signal switch contains an elaborate networking device that has to cancel brakelights while running a turn light. Often times the ground within the turn signal switch is lost causing your situation. After investigating such other possibilities as fuses and loose grounds it may become necessary to replace the turn signal switch. Thank you, Dana

Wrong replacement bulbs.

check blubs if the center light works should be working side brake lights

faulty switch

Turn signal switch. With you foot on the brake have someone stand behind the car. Wiggle the turn signal lever and see if the the brake lights flicker.

Its Accessed Through The Trunk Pop It And There Will Be Either A Panel To Remove Or Carpeting Material To Move Aside And You'll See The Wiring Harness With The Light Twist And Pull To Get The Bulb You Want Out.
