Default headlights wont work

Hi :( , so i noticed my head lights out, checked the fuses..good, relay...good. the light sensor reads that its day time so it seems to work. i can use high beams if i turn my lights selector from auto to on. and i can use my fog lights at night but during the day they are shut off on auto by the day light sensor. Could it be the beam selector relay? any ideas?

Are the low beam bulbs any good? You didn't say if you checked them or not.

Try replacing relay 47.

Here is the wiring diagram:
