Loose connecting wire?
Blower motor or resistor pack going bad?
For the record, I have the EXACT same problem with my 2003 Deville. When the blower motor fails to work, I can open and slam the front passenger door and it immediately starts working. Once it starts working, it will continue to work for as long as the car is running. If I turn off the car, it is a coin flip as to whether it will work when I restart the car. If it does not, I can slam the passenger door again and it will start working again until the next time I turn the car off.

Will a 99 Cadillac deville radiator work in a 2000 Seville
No, the seats in a 98 Cadillac Deville are all electronic so they cannot move manually. You will have to get the electrical components fixed before the seat will move.
