Help With 93 Concorde!!

[hickerx2]

Hello all.
I'm at my wits end trying to diagnose this problem. I hope somebody's run into it before so I have a direction to look anyway.

1993 Concorde, 75000 MI, 3.5, Immaculately clean.

Every single device in the car works properly with the exception of the instrument cluster. Fuses and sockets are all checked OK. I pulled the IC out to check the solder connections, all are good. No power whatsoever from the left-side connector behind the IC. I have nothing at all in the IC but backlights and high beam indicator. No PRNDL indicators, nothing. I've tried to trace the wires from that left-side connector but I can't find where they go. Tried disconnecting the battery to reset BCM..no good.

Can anybody give me any insight or direction whatsoever? I would be forever endebted for some guidance. Although the car is in fine condition, I'd like to get around paying a dealer more than it's worth to fix it.

Thanks very much!!

What color are the wires, for the left side connector?

Just wanted to add, the orange wire carries voltage for the IC lighting, but, because you said you had back lighting, I'm not sure if that is your problem. The black wire is ground. The orange wire gets it's voltage from the body computor. That doesn't mean the body computor is faulty, you would have to check circuits at the body computor.

There is:

orange, red, black, grey, purple(I think).....can't recall the other one.

Where exactly is the BCM?
I can't seem to find it.

And....am I assuming correctly that if there's power coming out of the BCM, the problem lies in between the BCM and the dash?

Do you know of any fusible links in that run?

Thanks very much for the help.

My info shows the BCM to be passenger side, under dash. I'm not sure what all you need to remove, it may be behind the kick panel.

The diagram doesn't show any fusible links between the BCM and the IC, but, there is a junction, several circuits get their voltage from the same source. I don't have the location of that junction.

Thanks very much for the help.....
I'll see if I can find the BCM again
