If it is like my 1992, and it may not be, the high beam switch controls a rod that goes down almost to the floor. The dimmer switch is mounted to the steering column and mine is from a 1989 Chevrolet Truck. I believe it is part number 26019660. On mine the adjustment of the rod is critical. When mine started failing. I lost all my headlights and jumpered across the switch to get the low beams working so I could get to Yuma and find a Chevy dealer.
