Sorry for the generic title of this message I didn't'[t know what else to call this. I have a 93 Honda Civic EX coupe. For about a year now when I turn the headlights on, the interior lights and tail lights would not come on. In order to get those lights to come on I would turn the knob for the lights about halfway between all on and just parking lights on. I figured the knob was just bad and didn't worry about it too much, I mean the car is old and it seemed like a small thing. Well over the last few days the tail lights and interior lights won't come on at all now, even with my play with the knob that turns them on. Here is what I am worried about, what if the knob was working just fine and me messing with it was just shorting out a circuit that allowed all the lights to come on. I am guessing there must be a relay of some sort that turns all of the lights on. What is this relay called and where is it located? I would like to replace it, but have no idea of what would control these lights. As of right now the car has headlights when the knob is turned all the way on, but never has tail lights or interior lights. Thanks in advance for any help.
