Pull the connector off at the wiper motor, and see if you have power there, with key on and wiper switch on.. If you have power there, either the motor is not working or the ground for the motor is not good.
I guess these older cars had relays for this? Or maybe just a fuse, like 30 amp?
I don't know, if it's a common problem, you may have to find out through an old car guy, like a retired cadillac mechanic. Or, I'm sure there must be an enthusiast's forum for older cadillacs, if you google cadillac.
Good luck.
