Hello all. I’ve got a 2011 Toyota Corolla S. The dome light buzzes when it dims. No buzzing when manually turned on and off. What could cause this?

Bad ground. Remove the lens cover for the dome light.

Try a new bulb!

The two most common causes for the buzzing sound are a failing bulb or a damaged fixture. Start by simply replacing the bulb and you might solve your problem right off the bat.
