Cadillac Repair: Digital Dash Problems, cadillac seville, coolant level

Question
I would like to know what's wrong w/my car, I was driving it yesterday and my dash, all electrical went out, I have a 94 Cadillac Seville. I can't tell how fast I'm driving, how much gas I have in my car, the coolant level or anything, I thought it was the fuse but my next door neighbor (who's been working @ Nissan and on cars, for the last 14yrs says check a forum) so I'm asking you guys

Answer
IS or HAS the CHECK ENGINE light ever illuminated on the dash panel ?.

Do you have ANY lights that work when you are starting the engine in the display ?.

The most likely cause is either a blown fuse, a faulty CENTRAL POWER SUPPLY, FAULTY DIGITAL CLUSTER or a wiring problem fault.

We can perform all the tests necessary to diagnose this problem and if it turns out to be a faulty speedometer cluster it will have to be sent out for repair.

You will need simple electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture. I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
