Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your STS. If the high beam icon appears but the lights don't illuminate, the issue could stem from a faulty dimmer switch or a problem with the high beam relay. Since you've already checked and replaced the fuse, it's worth testing the dimmer switch to ensure it sends the proper signal. Another possibility is that both high beam bulbs have failed or a wiring issue affects the circuit between the switch and the bulbs.
