    No High Beams

    My car- 70k miles- has no high beams. The blue indicator lights up briefly, but no brights. Is there a relay that controls the brights? Or could it be as simple as burned out bulbs? I was operating under the assumption they work in concert, so assumed blown bulbs were a non-factor. Am I ignoring the obvious?

    Do the DRL's work? I think a good starting point is to try new bulbs. I was surprised how often my high beams bulbs have blown over the years considering I hardly ever use them until I realized that they are also used for the DRL's. You could even swap one from the low beams to try it.

    There are high beam relays in the instrument panel fuse block on the passenger side.
