When I turn on anything, regardless what is already on, the lights dim for just a second and brighten right back up. So I step on the brake the first second all lights, interior & exterior, dim and brighten back up even though the brake is still on.
Another example, I turn the turn signal on. All interior and exterior lights dim & brighten oppositely ofthe blicker lights. And so on. Sometimes the dim/brightness is really noticable, other days it is unnoticable. Comes and goes in cycles to some degree. The battery is apprx 6 months old and is the propper battery according to the car specifications. Any ideas are greatly appreciated. Thank you for your time, Wendy
