1994 GMC Suburban Turn Signal Troubleshooting (check in this order):
· Check Fuse
· Check Bulbs
· Check Flasher Relay
· Check Turn Signal Switch in steering column
· Check switch on brake pedal
· Check license plate light bulb and wiring
· Check all wiring harnesses and wiring for shorts
Most likely its the fuse or a burnt bulb breaking the circuit. See sources and related links below for bulb information. Sometimes the license plate and/or the trailer hitch is wired into other circuits and can cause issues in other areas. Sometimes its wires grounding out somewhere on the vehicle. See sources and related links below for bulb information. See owner's manual for location and identification of fuses.

You probably have a turn signal bulb with two filaments one for the turn signal and one for the brake light. If the ground connection is bad on the turn signal circuit then the current would need to find another path to ground. The only other one available is through the brake light filament to the ground on the center brake light. Try removing the taillight assemblies from the vehicle look for what is probably a black wire screwed to the body or a circuit connection and either tighten the screws a bit or clean the connections.
