djb300 Posted June 9, 2010 Share Posted June 9, 2010 2003 ES 300 - Both low beam headlights stay off when the headlight switch is in the ON (top) position. The headlight icon appears on the instrument panel & the high beams work when the headlight switch is moved. DRL and all oter headlight switch related lights work fine.

cduluk Posted June 10, 2010 Share Posted June 10, 2010 Could be a fuse. Try looking in the manual for the correct fuse and give it a check. Does your ES have the standard halogen lows or are they HID? If HID, the problem could be with the bulb ballasts (igniters) or the bulbs themselves. But i find it extremely odd that both ballasts or both bulbs would go out at the same time. Did they go out at the same time? Or gradually? My guess is the fuse has blow. Rare, but my best guess.

djb300 Posted June 10, 2010 Author Share Posted June 10, 2010 I should have mentioned that I checked the fuses before posting. Both low beams went out at the same time. Could there be any relays involved, if so, where are they? Quote Link to comment Share on other sites More sharing options...
cduluk Posted June 11, 2010 Share Posted June 11, 2010 That i don't know If you can find an electrical diagram for the ES that might help you find it. Not sure where that might be located either, sorry :( Quote Link to comment Share on other sites More sharing options...
