Some time back I found some data on a similar website suggesting that the Day Light Running circuit board, just under the steering column, developed cracks in some of the soldered joints. Your high beams should also be affected with loss of day light running lights.
Resoldering repaired the continuity of the circuits. Ours is now working quite reliably. Some of the defective areas developed slight brownish discoloration, that's how I was told to recognise the areas to be resoldered. Hope this will help you solve your problem.

I had the same problem with my daughters 1998 Cavalier and found that the salt used on the Michigan roads and corroded through a wire. The when the light are used for driving lights they are hooked up in series on the 12v line and the wire between the lights had corroded. It has been a while and don’t remember exactly the point where I found the problem but it was by the driver side head light.

Check your DRL relay that is located in the fuse box. Also check the connector under the battery box for corrosion. (Not a smart place to put a connector) GM really messed up with the wiring on the 98-00 cavaliers headlights.

SOURCE: Drl and high beams dont work
Check the bulbs -- the daytime running lamps use the highbeams on the resistor -- There are two filliments per bulb one high; one low. If both high beam filliments are out nothing will work....replace bulbs if this is the case.

1996-99 chevy trucks.There is a diode, located under the dash between the steering wheel and the radio, fastenen to the round dash bar. The bolt that holds it on, threads into the top of the bar, it is near impossible to get at with a wrench. It is a finned block of (usaully black) aluminum about 2 inches squared 3 inches long. I found a easy way to get it out. Looking up you will see two tabs bent holding the diode in a bracket, bend them out of the way( you may have to bend the bracket a little aswell) and with patience the diode will slide out of the bracket, then disconect the electrical plug-in. I have found that this is the main reason for day-time driving light failure
