Q: Why does my interior lights flash on and off sometimes when I flip my dimmer switch?

asked by on

Why does my dome light flash on and off sometimes when I flip my dimmer switch? And my dash lights stay dim some times?

My car has 135000 miles.
My car has an automatic transmission.

Hello and thank you for contacting Your Mechanic.
The dimmer switch has a connection for the dome light and controls the dash lights with using resistance. The problem is the dimmer switch contacts have corrosion inside them and have created a cross path of current to the dome light. I recommend replacing the dimmer switch. If you need assistance in removing and replacing the dimmer switch, seek out a professional, preferably a Your Mechanic professional to help you with your dimmer switch.
