    Default Rear right-hand tailight not working, already tried new bulbs???

    Hey guys, I got a new problem. On my 1990 Suburban my rear right-hand blinker/tail light quit working about a week ago, so I put new bulbs in. But this time, that didn't fix the problem. Could I have an electrical short or something somewhere?

    Check inside the bulb socket for any scorching.
