Remove the sensors in the door jams ????
Don't waste your time...that will accomplish absolutely nothing.
the IOD fuse (#12 - 10amp) feeds out of the junction box (fuse box on side of dash) on 3 wires -
Connecter C2 - Pin3 - Pink wire (20 awg)
This feeds the Underhood light only.
Connector C3 - Pin 6 - Pink wire (20 or 22 awg...model options dependent)
This feeds the overhead console and (if equipped) the left and right visor/vanity lights.
Connector C7 - Pin 9 - Pink wire (22 awg)
This feeds to a wiring junction #5 (At the left side of the instrument panel) which feeds -
a) Splice 310 (I believe this is behind the left kick panel) which feeds Power mirror switch, dome light and cargo lights.
b) Data link connector
d)Glove box light
If possible/practical, I would disconnect each of the 3 wires from the fuse box, one at a time to isolate the problem circuit and minimize the search area, then trace from there.
Good luck and keep us posted.
