In my 2012 impala both low beam headlights are out also means no drl but both high beams work any ideas

 

with the car running in gear and someone holding the brake....check both the dtrl fuses
turn the headlight switch on anc check both low beam fuses...report the result
if all four have no power check the low beam and dtrl relays. if the relays aren't clicking on or off either the relays are bad or the bcm isn't providing ground to turn them on. the relays may be part of a printed circuit board in the fuse box. if they are its more involved.
