1994 Cadillac Seville

I have a 94 Cadillac Seville and the entire dash is out. It is both analog and some components are digital. The gauges doesn't work and the blower fan is always on and I can not shut it off. I checked all the fuses and they seem to be fine. I would like to know what the cause of this is and how much do you think something like this will cost to fix.

Thanks in advance.
