HI can somebody please help me. 2 Days ago i was driving home from my mothers and all the sudden the low beam headlights went out. High beams worked and fog, but no low beams. Some good guys came to my help. we checked every fuse available.. nothing turn on and off.. nothing. One guy told me that it could be the light switch.I drove home with high beams. Got out the next day they worked just fine, then they went out again... please help i dont know and i just bought a new switch from rockauto. Thank you!:bonk:

Try swapping relays 45 (cooling fan) and 46 (headlights) in the front fuse block and see if they behave a bit better. It could be that relay starting to go bad, and needing to be replaced. :m2:

99% chance it's the relay, not the switch or the multifunction stalk. Probably not two lamps going out at the same time, or two fuses (left and right are fused separately).
