Answers :

Here is a wiring diagram. Are the bulbs for sure good?

hope you can read it.
Have you checked all the bulbs? you can check the turn signal lamps by simply turning on the four way flasher. if all four lamps are flashing, then check the turn signal flasher unit. GM usually put them on the fuse box under the dash. check the owners manual.
check the brake lamp switch. it is mounted under the dash half way up on the brake pedal lever.
