I recently picked up a 2008 Pilot and noticed that the front vent, rear defroster, fan speed down, and fan speed up do not light up on the instrument panel at night. I'm assuming these are supposed to light up as it has been this way since I bought the car. When you select the front vent or rear defroster it lights up indicating it is on. I checked fuse 9 on the driver's side as this is for the instrument panel and it was good. Any other idea?
