WHY DON'T MY LOW BEAM HEADLIGHTS WORK?

2007 Buick La Crosse • 85,000 miles

My low beam headlights don't work, high beam works and running lights work. I replaced the low beam bulbs and checked the fuses and they still do not come on. I checked the old bulbs with a meter and they are ok. Can you tell me why they are not working and how much it will cost approx. To get it fixed?

The relays may be bad or you have a bad ground. I am giving you the headlight wiring diagram so you can find relays and replace them as well as check grounds.
