Cadillac Allante power issue
 

Allante Guru's,
I am currently working on a power issue on a 1990 Allante. When I start the vehicle, the dashboard does not lightup, the trunk pull-down motor does not operate, and the interior fan blower motor does not come on. I checked all of the fuses in all three locations and they are all good. I checked for shorts to ground from the fuse locations and found none. I am trying to follow the schematics in the manual but, can't get a common thread for the symptoms. I am leaning toward the CPS central power supply or the BCM body control module.......Is there any way I can check their integrity before purchasing either or both? Any help would be deeply appreciated!!

Desperate in NY:confused:
