I had to replace my right side high-beam bulb a few weeks ago. No big deal to do. As mentioned, remove the storage bin and reach in through the opening. I did both sides since I went to the Silverstar bulbs as an upgrade for lighting. The right side was much easier to replace then the left side do to the wire harness routing on the left. Left side had very restricted hand access the bulb and the removal of the headlamp sealing grommet on the left was the hardest part of the replacement.
This was done on a 2005. Your's may be completely differnet if the wire harness routing is not the same as mine.
