troubleshoot drivers side low-beam headlight not working, 2013 buick encore

What is your question?

Failed to disconnect battery while working on headlight drivers side. Shorted out and blew bulb resulting in smoking in the headlight area. All other electrical systems and lights are still working. They is no fuse for the regular beams so I am not sure what else to check. Quick stop by dealer and they first checked fuses and did not seem to know there was no fuse for low beams. They say they need 5 hours to check for wiring short, does this sound right or is there another switch or item that could be checked.

What makes this problem better or worse?

all other items working
