SOURCE: 1998 gmc sierra brake lights
did u check that they not burn?if not you should Check the wires going into the steering column if you don't have separate turn signal lights and brake lights because if they use the same bulb then the turn signal may be bad. If I remember correctly that particular car doesn't work this way, but I include it just in case.

SOURCE: gmc sierra turn flasher location
The flasher on this vehicle looks nothing like the flasher's of yesteryear. It will be located behind the drivers side knee bolster(under the steering wheel). It will be a small black box that is about 3 inches wide, 2 inches deep, and 1 inch thick. It may be somewhat difficult to locate because on some of the GM trucks they actually hide it behind the guage cluster bezel but to the left of the guages. Let me know if I can help you any further.

it seems you have a short in either one of the lights or interlock. all are connected to the same fuse. trace the wiring from the fuse box back to the component. Using a test light test in between the wires. check for any obvious breaks in the wiring.

ASE mechanic here:
trying checking the turn signal flasher, the fuses, if all work fine, most likely cause is the multi-function switch.
