It could also be the switch. Or coincidental failure of both bulbs. Check with a test meter.
..

These links show multiple fuse boxes and fuses which have something to do with daytime running light and lights.

Why ? Both hi & lo beams not working ? Either side ? Has four fuse's , two relays . headlight high relay & headlight lo relay . Both relays are controlled by CPU located inside the IPDM - intelligent power distribution module . located under the hood in engine compartment . Free wiring diagrams here http://www.bbbind.com/free-tsb/ Enter vehicle info. Year , make , model an engine size . Under system click on lighting , then under subsystem click on headlamps . Then click the search button ,then the blue link's one at a time . Looking at the wiring diagram i'd say your problem is going to be a little more complex then just replacing fuse's .

From Info I have looked at I believe under hood micro switch relay 35 is for low beam and 34 is for high beam. It also looks like you have a different fuse for each light. The relay are for both low beam or both high beams. each headlight has its own fuse. I believe #4 fuse under hood is for passenger side low beam. fuses 1-4 under hood are for the four headlights as I understand the info I have seen.

HEADLIGHTS NOT WORKING

It can be faulty headlight switch or issue with its wiring. Or its faulty head light fuse.

These will help.

Thanks.

THE HEADLIGHTS DO WORK ON A DIFFERENT WIRE AT THE SWITCH, ALSO THERE IS A RELAY FOR THE HEADLIGHTS USUALLY LOCATED IN THE MAIN FUSE BOX UNDER THE HOOD. CHECK THE RELAY FIRST, THEN YOU MAY WANT TO GET A WIRING DIAGRAM OR CHILTON MANUAL TO CHECK THE WIRES COMING OUT OF THE SWITCH.

If your headlight switch is bad,this video will show you how to replace it.">

Day time running lights run low voltage to the high beam bulbs so it sounds to me like you need two new bulbs or you need to check the fuses and see if any need replaceing.

Appears that there is a relay in the system as well, so check & swap same number relay if you can, i'll dig a little deeper in meantime.
