What should I do if my brake light and turn signal don't work I've switch the fuse change the bulb and still nothing I have a GMC Sierra 1500. The turn signal don't come on when I turn the lever on.
The switch in the column is bad,meaning blinker assembly.
The brake light all so runs through it,
Could be its and old junker I'm thinking it could be a short in the wiring or the column
