There are several reasons why the rear reading light of the Volkswagen CC cannot be turned off: Switch set to always on: The interior lighting system generally has three modes: always on, always off, and lights on when the door is open. It is possible that the switch is set to the always on mode, which prevents the light from being turned off. Switch damage: If the switch is damaged, the reading light will remain in the on state and cannot be turned off. Wiring issues: Driving with the interior light on for a long time is not advisable as it may interfere with the driver's vision. Wiring problems can cause the reading light to stay on or off, in which case the voltage and resistance of the wiring need to be checked.
I've helped my neighbor fix this before. The most common reason why the rear reading light in a Volkswagen CC won't turn off is that the car door isn't closed properly. A loosely closed trunk lid can also trigger it. Try spraying some lubricant on the door latch mechanism? Older cars tend to accumulate dust and get stuck. The rotary switch itself might be jammed in the ON position - try poking a toothpick into the switch crevice to remove dust. If that doesn't work, you'll need to remove the light cover to check the wiring. Maybe the technician messed up the wiring when installing the dash cam last time, or rodents chewed through the insulation causing a short circuit. Finally, don't forget to check if the corresponding fuse in the fuse box has blown - replacing a $0.70 fuse might solve the problem.
