I had a similar problem with my 2000 Malibu. the headlights (not just the daytime running lights) would come on all the time. I finally fixed the problem by cleaning the sensor that's in the dashboard vent. I used a cotton swab soaked in mineral spirits to reach down into the vent and just wiped it thoroughly. The lights now work like they're supposed to. Daytime Running Lights during daylight. Regular lights come on when its dark.
