Change the headlight it is burned out. It is also possible that the headlight/turn signal switch on the steering column is burned out. If both of your headlights are new and the low beams still do not work, check this switch. (I just replaced mine for $40 Cdn.) Could be a broken wire too. Check under the battery, that's where mine broke off. I am having the same prob. with my 97 sunfire. my daytime running lights do not turn on nomaly and the highbeam indicator is always on. when i turn my highbeams on all the lights go out. if i have my low beams on and i turn my left signal on the indicator light will flash along with my left turn indicator. i am asuming it is a short in the wiring. i will have to check. Make sure that your just not noticing it. It took me awhile to realize that when the car is in drive, the headlights come on automatically. I thought they were broken. Check that before you spend alot of money.
In the area in front of the right front wheel below the headlight.
