interior lights flashing

Turn your headlight switch all the way to the left, you will feel a resistance, that's your interior light switch. Turn that switch left then right then left then right several times. That will put wear or friction on the reostat inside the switch. (That switch rarely gets used) If that doesn't take care of the problem, if it's just one bulb that's flickering check that bulb. Good luck, -dragcar-

It's your chime module, located behind the driver side kick panel by your feet. Might try cleaning up the plugs before you go buy a new one. The terminals corrode and lose connection sometimes and if you're lucky just cleaning it will solve your problem.
