Hi all, my right Headlight has stopped working and can't quite figure out why.
1) I replaced the bulb with the exact same kind of bulb - this did not work.
2) When replacing the bulb I saw the side of the connector/plug that the light plugs into was actually melted a little on the side, I replaced the connection/plug part - this also did not work.

I've opened the fusebox and after doing some research on the forum found that the pink fuses are for the headlight, but pulling ALL fuses out of the fuse box with the lights on, actually had no effect on the lights that are still working. So I'm confused if the fuses effect the lights at all?
To confirm I AM looking at the fuses in the correct area (i researched on this forum but cant post URLs since I am a newbie)

Since none of the fuses pulled out of this only area with fuses worked, my question is, is there a secondary fuse tray UNDERNEATH the one highlighted here?

Some other research has lead me to believe there may be some fuses behind or by the glovebox? I can't seem to find that in the manual though.

My only other idea is there may be a faulty wire? Any help would be greatly appreciated, thanks!

Check the ground wire, or bypass it with a piece of wire to a ground point and see if that works.

My 08 had the passenger side go out a few years back and it was the ground wire. I just wired up a bypass to a nearby ground point. Last year, same thing, but on the driver side.

My pat has all kinds of issues with wiring getting corroded and failing, causing a mess of electrical issues.

If one headlight is working, then its not a fuse. Both are powered by the same fuse.

A melted connector can also be an indicator of a burned open headlight wire somewhere. Check any other connectors and wires associated with that light.
I agree with spooge, first check the ground wire and also for any traces of corrosion in the bulb contacts.

Corrosion or an intermittent contact connection in an electrical connector can present an electrical high impedance between the contacts which can cause heat and arcing ending up in a melted connector if severe enough.
How did you splice-in the new connector? If crimp-on lugs were used, i'd double check them too.

I also looked up the fuse panel diagram for a 2008, can't say why pulling that 30 Amp 'head light' fuse didn't kill the good light. Seems to me it should of at least according to that diagram.
