Does the air control switches have lights? I can't see anything at night.

Hello, Begin by checking your fuses, as you certainly should have illumination on the buttons. If your fuses are good, you may have a lose connection, defective headlight/dimmer switch, or problems along the circuit. The best method if the fuse has blown will be to inspect the circuit to find where power is lost with the headlights on. To do this, you will need the wiring schematic from the service manual, but alldatadiy.com has this information as well.
