Seems like the brake/tail light bulbs are backwards. the large filament(brake/ blinker) is staying on when the lights are on rather than the small filament(running lights).

SOURCE: replace tail light bulb

open hatch, look for two screws, remove , push tail light gently back and forth to release from clips pull light assembly out , twist bulb socket to remove from housing, replace bulb.

You have a ground issue.Current from another circuit is running through the lights to get to ground. this causes them to burn out quickly.You need to do a real detailed visual check.A good component wiring diagram and component locator is a requirement here.

looking at your schematics and , you say tail lights don't work , you didn't mention if front parking lights and license plate lights are working , they all come from the same source , a black /yellow wire , a good clue if front work and rear don't , please advise .if fronts work then you have a open circuit somewhere between junction S118 (near breakout for left headlamp) and rear sockets.

you probably got the wrong bulb
those are usualy a different number higher wattage, they look exactly like an 1127 but are a 2027 or even a 3027 check the bulb base it has the number printed on it

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
