2. Malfunctioning switch: The headlight switch or the multi-function stalk may be malfunctioning, preventing the low beam or driver's side high beam from working properly.
3. Electrical issue: There may be a loose connection, blown fuse, or faulty relay related to the low beam or driver's side high beam circuit. Check the wiring and electrical components for any issues.
4. Damaged reflector or lens: The low beam reflector or lens may be damaged, preventing the light from being properly projected. Check the condition of the headlight assembly.
