I think there are 2 fuses for the beams, depending on the setup. Did you look through the manual carefully?
I'd check those fuses first. Might try looking for a corroded connection and/or scrapes along the harness.

I am having the same problem with my '00. the high beam fuse keeps burning out as soon as I turn the high beams on. Any ideas were to start looking, do you think it is a break in the wire somewhere?
Thanks for any help
