It sounds like it's your Headlight switch has gone bad, I'm thinking that the high beams are the daytime running light which is the same as your High beams.
If you go to Auto Zone or Parts Source, they have the replacement switch with step by step instructions. Try not to run your Headlights too long from your running light's. The headlight's draw more amps then the running lights and can melt the wire which can result in a short and worst a fire.
If you remove the headlight switch from the dash, check the orange wire for power, if there is 12 volts. Good chance's are that the switch is bad, common on the GM's.
Good luck and hope this helps. I believe they go around $70.00 or do what most guys do. Salvage Yard range from $10.00 to $40.00 and there also have warranty.

Check your headlamp relays under the hood, should be located on either the L/H or R/H fender well , could be inside a black plastic box labled fuses and relays... there will be a label on the underside of the lid to this box locate the relays as per lables... please rate my help thanks...

well as a tech i dont recomend it but all you got to do is swap the wires on the headlamps at the bulb you will see 3 wires one is a ground the other feeds low beam the other high beam . take a test light and find the one thats hot and cut it and connect it to the other blade , leave only one wire on the low beam terminal so you dont short it out .

Testimonial: "Great info many thx"
Start by checking the fuses.Check both fuse boxs.Under the hood behind the batterie and Dr side end of dash.There would be seperate ones, lowbeam/hight beam.You can always check the bulbs by swaping them with the high beams.Just be sure not to touch the bulbs.Use paper towl to hold them.
