My headlight switch has started acting up. When I turn on the marker lights they work fine. When I go to the headlights they will only come on if I rotate and hold the switch a little past the "on" detent position. If I don't keep pressure on the switch the headlights will shut off (marker lights will stay on). I've seen how to clean the switch so low and high beam work but haven't found if I can address this problem. Has anybody had the same thing happen?
