2002 Chevy Cavalier front headlights

Believe it or not, if you are lucky, behind the lower left side of the dash in the fuse box, there are two seperate fuses for right and left headlights. Or check for power at the dark blue wire, it's the low beam power wire, also under the battery tray is a connector that corrodes, and the ground at the battery tray, thu a ground issue would cause dim light, not no light!
