Q: Headlights not working - 2005 Buick LeSabre

asked by on October 02, 2016

My low beams wont turn on but my high beams work fine. I dont think they are burnt out because if I set my alarm my low beams still flash. We have checked all the fuses. Any ideas?
My car has an automatic transmission.

Hello. A common fault is the combination / multi-function switch. This is the signal / high beam switch located on the steering column. If you need help having this checked, a qualified professional from YourMechanic can come to your location to inspect the lights issue and let you know what needs to be repaired.
