When I turn on my headlights, the left blinker indicator stays on and
solid even when I'm not using the left turn signel. I get the same
behavior without the headlights turned on when I use the left turn
signal. The actual blinker appears to have the same behavior as the
indicator. The right blinker functions properly at all times.

I hope there is a relay somewhere that I can replace. Anybody know
where that relay might be?

Does this sound more like an electrical short?

Thanks in advance,

John
