To better assist you is your model just the Envoy or the XLK? Also what is your engine size in liter?
Not trying to insult you... Just making sure you and I are on the same page..... Are you sure both light bulbs are still good?
Next, I show fuses 3 and 6 are 10amp for the low beams and fuses 5 and 2 are 10 amp for the high. You did check them with an ohm meter and they are good.......
Next, I also see Relay number 46 is a relay for the low beams. Have you checked that?
