After reading the wiring diagrams, I tend to agree with your technician. But before I say he was right, I need to you to check all these fuses, and also make sure that your side markers and taillights turn on when you turn on the markers (not the headlight). If the markers work, then your headlight switch is OK, it must be one of these fuses..
Under the hood, fuses # 4, 6, 8, 9, and 12.
Under the dash, fuses # 5, 7, 11, and 15.
