The high and low beam lights use the same power source, so if the low beams work the high beams have power.
There is a low and high beam relay controlled by the dimmer switch.
If the low beams work and the high beams don't, and the bulbs are good, check the dimmer switch and the high beam relay.

If it is like the 2002, one is in the engine compartment near the jumping post. The other is under the back seat.

Hi Violinlovr,
If memory serve, you'll find one box under the hood and another the same side as the steering wheel which is accessed by removing the plastic storage locker....Open it and gently pull down on the top so that it swings all the way out.
