I just replaced the lights on my 05 a month ago, yesterday the right low beam went out, so i figured it was just a bad bulb, bought new one today and it still doesnt work, i pulled all the fuses that had anything to do lights and they where all fine..... Left low beam works, and both the highs work. Im stumped, my next guess is a loose wire or a cut wire somewhere.... Any ideas?

 

My model year has a separate fuse for each low beam. Are you sure you checked that? Checked as in tested, not just visually inspected?

 

Yes i checked both the right and left low beam fuses. i only visually inspected the fuses, i dont know how i would test them

 

Most digital volt/ohm meters have a continuity test mode.

Or, if you have a test lamp, turn on the headlights and set them to low beam and probe the backs of the fuse. If both sides cause the test light to light up the fuse is good.

 

Ok, or i can switch fuses around

 

anyone else have any idea? i still cant figure it out

 

You have a broken wire somewhere in the circuit.

 

I have had this problem on a Plymouth Voyager and on my F-250. Both times it turned out to be a corroded contact in the lamp socket. I had to cut out the socket and splice in a new one.

 

Now that you mention the corrosion.... my lamp socket or whatever it is does have some in it, i sprayed wd-40 in it to see if it would help, but nothing

 

I fixed my head light, it was a bad harness, i ordered a pigtail kit from ford and its done just fine so far
