2002 Trailblazer LowBeams Out, Fuses/Relay Good

My 02 Trailblazer LS lost low beams last week, right after jump starting a guy with my car running. High beams are good. I checked underhood low beam fuses 3+6, swapped relays 45+46 (even tried a new one) and checked all the fuses in driver side 2nd row underseat fuse block: 4, 7, 32, 40, 50, 52. All are good and low beams are still out.
Anything else to try other than thinking that both low beam bulbs somehow burned out simultaneously? Thanks... :undecided
