The headlights, and therefore the dimmer switch, are on a separate circuit from the dash/parking lights.
Does the fuse blow with
just the park lights on, or when you pull it to headlight position?
If it is when you just pull it to the park light position, it may well be one of the parking lamps causing the problem, in the front or the rear. Hard to say, but you'll prolly have to start looking there...
