Your headlights are controlled on the ground circuit. The voltage to the lamp is hot all the time. I'd check the actual voltage reading at the lamp. If the connector is labeled ABC, B is voltage to the lamp. A & C should be grounds for bright or dim. If the problem is on the ground circuit, can't tell if it is the multifunction switch or wiring circuit, somewhere.
