One Headlamp Dim

[riverat440]

Hi all, has anyone had any experiences with one dim headlamp on a 00 Grand Vitara? I checked the lamps themselves, and the wiring where I found different values at the plug with the lights on and traced back further. I found 4 relays which all seem to be working. There seems to be a diode behind the glove box which I wasn't able to find. I'm hoping someone has had these same issues and shed some light on what is going on before I start ripping and tearing. Looks as if this the last stop before getting to the switch itself.
