2010 Corolla Low beam Headlights not working.

2010 Corolla Low beam Headlights not working. Checked fuses, bulbs, now what.
I have dash lights, tail and park lights, day time running lights high beams but no low beam lights.
Tested bulbs on battery charger they work.
No power to light socket.
Where is the headlight relay?
