Instrument panel

I do not mean to insult you, but have you checked the knob/switch? I ask because my wife had the same issue with her car once when she first got it, and it actually took me a minute to find the switch for her. There should be one near or built in to the headlight switch. Should be "K" in the first image below.

Well it was worth a shot. I would take the fuse out and either replace it or test it with a multi-meter. Sometimes they can blow and still appear to be good. Basically it would burn/blow in a spot in the fuse that makes it hard to see. It is unusual, but it happens. If that is not the problem, then you will want to make sure that there is actually power getting there. You would turn the key on, headlights on, and use your multi-meter or test light to probe the contacts and see if you get twelve volts there. If you get twelve volts there, then the problem is somewhere between the fuse block and the dash. No power there indicates a problem either in the wiring, the body control module, or the switch itself.

So check that and get back to us. We will go from there.
