This car has 4 different fuse boxes, scattered
around the car. I do have it confirmed as being a
ground issue. I noticed the map lights didn't work, in
addition to the other systems. Checking the very
poor wiring diagram in the Haynes manual I have, it
shows 3 wires to the map lights in the mirror, 12+,
door switch ground, and a ground for map. Diagram
shows a 2 position switch, normally connected thru
the door switch ground and then switched to the
ground for map. It gives no ground location or
designation like GM does, such as g23 or g206 that
would show the grounding point and location in the
ground distribution Chart. I connected a wire to the
ground wire for the map at the connector and the
other end to a good ground point with the ignition
on. I immediately got my blower, defrost, auto door
locks, and chime back. It showed I do have a broken
ground like I thought, but still don't know where. This
car at some point had a aftermarket remote start or
security system on it, due to the ton of scotch locks
and cut wires coming off the ignition switch I
replaced. My thinking now is the tech needed a
ground for his system and instead of drilling a hole
and placing a screw for his ground, he probably cut
a ground wire and spliced his wire in with a butt
splice connector and when I had the column down
to replace the ignition/dimmer switch, I either
dislodged it or pulled it completely apart.
