Low beams aren't working...new bulbs...all fuses are good...any suggestions.

I had the same thing happen to me, what I did was with the lights on pull the bulbs out and pushed them back in. I think it might of been contact issues with the new bulbs I bought. Just be forewarned wear gloves those bulbs get hot when they turn on. Not sure if this will fix your problem but it's worth checking out.

do the dtrl run throught the low beams on your model? the z88 option does. if yes, do the dtrl work? another item to check are the dtrl relay and hdlp low/hid relay. do they click when energized? the bcm grd controls both of these relays, so if the power is present to the relays and the relays are good; make sure the bcm is providing grd to the circuit.
