are you getting power to the high beam fuses in the underhood fuse panel? if you don't have power to the fuses the relay may not be turning on.You have a low beam relay and a high beam relay in the same fuse panel as the high and low beam fuses. See if the high beam relay is clicking as you turn the high beams on and off. If the relay clicks every time but you never get power to the high beam fuses you either have a bad contact in the relay of you don't have power to the C1 pin on the relay. switch the high and low beam relays to see if there is a problem with the relay. If switching the relays doesn't make any difference then you will need to verify the high beam circuit is working.
