It is most likely the tail fuse. The dash and tail lights are usually on the same circuit

The dash lights will dim when the head lights come on. Check for a dimmer switch on your dash. It allows you to adjust the dash lights so they are not too bright and affect your nighttime vision. It may be set too low.
The GMC dash tail and parking lights are on a different fuse from the brake lights. Check the fuses for a possible blown fuse.
Check the fuses.

You will need to check the ground wires. A loose ground wire can cause the lights to work sometimes and sometimes not to work.

its just a fuse, look for a fuse panel there are two. one under the dash and the other under the hood.
