My lowbeams/running headlights are not working but my high beams are?? My car is a 1999 sunfire sedan.

check the lowbeam headlight relay in the engine compartment. See tip here on how to check: http://www.fixya.com/cars/r6053280-lights_out_lights_not_out_bulbs_ok


Let me know if you have questions.

Make sure you use the right light because the high beams and low beams use different lights. I think the low beam is H4531 and the high is H4532.

I have same problem but my low beam don't work and drl but my high beam work when flick.

is the problem solve?

have your mechanic check the daytime running light relay and control module as failure is common.

check the switch it self in the steering column mabe faulty and will need replacing. the high beam switch tend to go bad over time, some has better luck than others, it fairly easy to replace. the switch unit itself operate like a two way switch, one for flashing and other high beam.

do the high beams work?? ck the hi-lo beam switch at the steering column.

the filament on the low beam burnt out. but the high beam didn't. You have a filament for each. 1 for high beam and 1 for low beam in the same light bulb. You need a new head light.

check the wire connection for your lowbeams

perhaps i missed something here... lowbeams and daytime lights are about the same.... be that as it may... the merely obvious thing is that the low beams are burnt out.... next thing would be that the relay for the day time lights could be defective... it's often mounted on the firewall.

When you open the hood and look at the headlight assembly you will see 2 plastic gears, they take a hex tool, and the one to adjust the lowbeams is the outermost one towards the fenderwell of the car, the high beam adjustment is the one closest to the radiator.

Hope this helps.
