Take a look at this link regarding DRL system. I know it's not exact truck but most of it would apply to yours too. It should give you hints on what to test & how.

I got my daughter a 2003 Pontiac Sunfire. They are a lot of electrical work.
The problem is the wiring harness which splits and travels under the battery and the windshield washer reservoir. The wires oxidize and fall apart.
The low beams will work but if you turn on the high beams the lights will go completely out, right?
If this is the case I can pretty much guarantee that you will have to remove the battery, the drivers side front inner fender, the air filter housing, the air throat, and the windshield washer reservoir. You will then be able to open the wiring harness feeding the headlights. The wire that feeds your high beams is a pink wire. Test the wires from the harness plug (located just under the battery) to a point as close to the headlight as you can, Use a simple continuity tester. Also feel and bend the wires. If the insulation cracks and you see a green or lite blue powder then patch a new wire in.
All in all I found 4-wires which I replaced. Everything works now.

mdsarnes, The first thing that I would check is the fuse for the low beams located in the engine compartment power distribution box. (Fuse box) GM does have a legend written right on the cover so you know which fuse to check. Also, when the low beams are on try and wiggle the connectors to each bulb. If these dont work, replace one bulb and see if it works. If it does then take the same bulb and try it on the other side. If you have a test light then you can test for power at the plugs before you purchase any bulbs. Good luck with this.

There is a relay for the high beams that may be faulty. That relay is located in the power distribution box located under the hood of the vehicle in the engine compartment. The relay location will be in the "R5" position in that panel (see diagram of layout below). Other then that you could be looking at a bad switch or a wiring problem nut pretty sure this will be your problem. I hope this helps and good luck.
