One thing to try is "flash to pass", that is, if you pull the arm towards you, do the high beams come on? If they do but regular high beams do not work, then fuse 32 is blown OR the multifunction switch is bad.

If Flash to pass does not work either, I'd look at fuses 3 and 5 on the ICM (Fuses on end of instrument panel, below the cover that you access by opening the driver's door).

A bad multifunction switch generally fails on one side or the other. If NEITHER function lights the lights, I'd suspect trouble elsewhere.
If you had airbag or steering wheel (clockspring) work done, I'd suspect the connector to the multifunction switch did not get plugged in all the way when they finished work.
