Low beam not working on xf - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Has anyone had this same problem before? I dont have a multimeter so cant check it out where the problem is easily.

My right sidelight has not low beam but parker. The left side is fine. I replaced the bulb and checked all wires around it and they SEEM fine. Highbeam on the same light WORKS.

Any help would be great.

I'm 90% i had something like this happen, and it turned out to be an earth. There's a couple of earth (black) wires that go into a round eyelet crimp terminal that screws to the chasis above the headlight.

Hope that helps.

I never checked that! Im stOOpid. lol. It would make sense because it did work, then didnt, then did, now doesnt. Checking it now for earth.................

I had this problem too..

The relay box next to the battery should have 2 or 3 relays.

The relay closest to the windscreen operates low beams, then the next ones away does high beams, then the next one for fog lights if you have them.

The light started working for a few days and now isnt again. Earth is all good and i played around with swaping the rely boxes and it still doesnt work............so im still not sure what the prob is :(

What about the switch itself on the instrument cluster surround...have you tried replacing that or cleaning the contacts?

Can you jump power through the relay and get them to come on, also swap the fuse with another working one, fuses sometimes need to be reseated or changed.

The weird thing about it is it never turns off and on while driving. Only on for a few days, and off for a week or two then back on.

I will try what everyones posted.

Thanks
