1991 Chevrolet half ton pick up

NO BRAKE LIGHTS. Have all turn signals back up lights and running lights when headlights are on. Replaced brake switch under dash.checked fuse panel. Checked bulbs.Went all over with a test light and no luck at all. If anyone can help I would really appreciate it. Thank-you

    If you have trailer wiring, check this area first. Corrosion or bad connections cause issues.
    If you have power coming from the brake switch when applied(yellow wire at socket), but none at the brake light bulb socket, trace and replace wiring between the two. If you have power at the bulb socket, check the grounds(black wire).
