    Default need some Headlight help, having issue

    Just got into our 1999 GMC K1500 Sierra SLT and the headlights were off but the blue hi-beam indicator was on and buzzing. By buzzing I mean the same noise you hear warning you that you left your lights on while engine off/door open.

    I turned the lights on and the noise stopped but there are no headlights...high or low beams. No running lights but parking and turns work.

    Could it be fuses, relay...? Any suggestions would help for me to look at. We've been hit with another snow storm so I'm checking online to get good starting points before trying to screw around in the cold, with no garage and it getting dark outside. I just bought this truck couple weeks ago, last we used it was Tuesday to pull home our new camper. Everything worked fine then.

    I appreciate the help folks!

    Not sure about the noise issue.

    However, the headlights maybe do to a bad switch.

    I had put a higher wattage set of lights in my truck, and have had to replace the switch several times.

    Default issue resolved

    There was a short in the headlight wiring. $263 later and headlights are functioning normally.
