Wiring diagram for lights?

TechSuperstar · 09-06-2012, 09:29 AM

Recent problem: The passenger front side marker light went out. Tried new bulbs but doesn't seem to have any power. Anyone have a diagram or know where the wires go from there? I'm going to check the wires themselves first in case the light socket is bad but I doubt that.

Thanks

Actually, it's very common for the socket to go bad - the bulb gets hot and melts it. It can even melt the plastic lens housing.

+1^

They all power from the front SAM. Some with electronic protection/control & some fused ~ low beam only I think fused. All the rest electronic.

See your fuse diagram

It's also very easy to manually trace the wire. Half the wiring for the front lights looks like it was added aftermarket, so much of it is exposed.

+1^ again! The standard Schematic on that harness is of no help. I does not show routing.

Thanks! It was the socket. Didn't see anything melted but the metal clips that clamp onto the wire which the bulb plugs into was all corroded. That was probably the problem. Anyway, $10 later I have a new socket and a working light.
A $10 problem beats a bigger problem anyday!
