I'm stumped.  I tried to find a wire schematic that is large enough to see but had zero luck.

1- High beams work.

2- Low beams / day time driving light are out.

3- Bulbs are good.

4- There are two wires at each bulb and they're both hot to ground.

5- There is a multifunction switch / turn signal at the wheel.  There is also a manual switch on the dash.  Regardless of the position of the switches the low beams won't come on.

Where would you look first?  I had assumed the switches interrupt the hot leg but is it the ground?

Check the fuses. Chevys sometimes blow a fuse and act weird. peterbilt trucks do too.

The multifunction is your problem and is pretty common.

I replaced one a couple weeks ago.   It's fairly easy, if you're a contortionist.
