My cluster lights didnt work ( I thought the bulbs were burned out) so I take everything apart and play with the dimmer for a quick second to find out they are both good and when I put them back in they work. Then about 3-4 days later they stopped working. Before the hazard triangle would light up when I put the dimmer all the way to full, but now there is nothing. All my other lights work, head, brakes, tails, reverse, light inside. But my dash lights, hazrd triangle light, and my light behind the heater switches (but that never worked). What could this be? Faulty bulbs, bad connection, wire loose somewhere if so Where? I hate dealing with electronics but I need to see my speed at night!

Thanks,
