My high beams would come on at night whenever flipping the left turn signal, got to become a bit annoying, especially in traffic for oncoming drivers. If I fiddled with the lever it would go back to lows & the right side worked fine all along. It seemed to be a mechanical problem so I took the turn signal lever out for a closer inspection. Once again I started what seemed to be a simple task & didn't bother with a camera so no pics, but all it needed was to bend the brass contact strip inside the switch a skosh so the contacts wouldn't touch. Problem solved! I'm thinking I might have inadvertently crushed the switch last year when I swapped steering wheels.
