Cadillac Repair: Digital intrument pannel on 89 fleetwood, digital dashboard, intrument

Question
I've got an '89 fleetwood that has a digital dashboard that is not working.  I sold it at one time to some people who never finished paying for it and when I got it back, the dash was out.  I didn't find any fuses under the drivers side dash board that are out, but not even sure which one it would be since I don't have the owners manual anymorea and can't find a diagram online.  The Car was not running well when it came back but at this point I don't even know how much gas its got in it.  I've read a couple of other things about the radio and a connection to the electronic dash.  When I sold it it didn't have a radio in it because it stopped working and when I got it back, some wires were pulled out of the hole, so it sounds like they may have done what I've read a couple of other people have done, but since I don't know for sure I was wondering if there was some other way that I could test the instument panel to see for sure if it is fried.  I just want to make sure that there is not a fuse somewhere else that I need to check before going to the extreme of having to replace the whole pannel.

Thanks,
Bill

Answer
I can provide you with test procedures via pictures and directives.

Is there a radio hooked up IN the vehicle ?.

Most likely someone tried to put a radio in it and blew the dash assembly and or the BCM computer. Your most likely looking at $400.00 for the dash and $200.00 for the computer.

HOWEVER, tests MUST be performed FIRST.
