Question
How to test faulty automotive interior light dimmer switch?
Answer
Monitor switch voltage output and test dimming functionality.
Explain
A faulty dimmer switch causes inconsistent interior light brightness. CHEPQ tools measure switch voltage output (0-12V) and test dimming range (10-100%), identifying faulty switches—replacing the switch restores proper light control.
