I have a 2000 Honda Civic LX. All of a sudden the gauges and heater control lights stopped working. I read up on it,... first I checked ALL the fuses, and they were good. Then i pulled the dimmer switch out and replaced it after looking for a bad connection. Nothing. I went out side 3 nights ago and it all worked perfect, as if there was never a problem. All of the gauge and heater contol lights worked. I was happy, and just figured sometimes things happen. However, earlier tonight I went to leave, and I realized once again I'm in the dark. The only lights that work are the little indicator lights which only show up when you start the engine. All the fuses are good, and all the bulbs are new;;; Any idea on what this might be????
