The switch that adjusts the headlights only adjusts from five to three, then the light doesn't go any higher. If I move the switch quickly from five to one, the lights don't move. I've tried another switch, it doesn't make any difference. I'v had a headlight off to see if the adjuster was rusty, but it's clean. They both stop at the same time. maybe a wire problem somewhere, any ideas what might be wrong? The car is a 1990 80 4.2 12v. Any help will be gratefully received.
