Very possible the potentiometer (rheostat) for the dimmer has corroded. Try working the knob left & right a bunch of times rapidly. That will usually clean the coil to make sufficient contact.

As for the light switch. As noted, two clicks right turns on all lights. With the knob handle at 12 o'clock the lights are off. One click left turns on the right sidemarkers and two clicks turns on the left (or vice versa). The positions to the left only activate when the key is off. Those are the standing/parking lights for the narrow Euro streets, the idea is to leave the car illuminated when parked. The bulbs hardly draw any power and you could leave them on all night without problem.

The two clicks you feel when pulling out the knob are for the fog lights. The first click should activate the front fogs and teh sencond will activate the rear fogs if so equipped.
