If you haven't got your blower fan fixed yet, im sure it to be the same as mine, the blower motor relay which is out on the firewall under the big fuse block. take plastic cover off over the fuses and move the fuse block out of the way and you will see it staight under that. should be two screws holding it on.

    the problem is the blower control module or blower resistor as some call it. known by both names. just replaced mine on 93 pa. $126.00 including tax at O'reilly auto parts. It's under relays and fuses under rain cover next to firewall under hood. 3 small screws

Why does the cabin fan continue to run

If you have a variable speed blower motor, a bad motor speed controller can keep it running even with the key out of the ignition. See this post on blower motor controllers. https://ricksfreeautorepairadvice.com/blower-motor-wont-shut-off/

Replaced blower motor, now runs continuously.

Run's continuously ? High speed , low , med 1,2, 3 . ????
Probably the high speed relay contact's stuck closed . The fuse for the high blower is hot at all times , low blower fuse is hot only with key on. It sparks becaused the motor turns on . If it had a short the fuse would blow . The blower motor relay is part of the resistor pack near the blower motor .

1991 olds 98 regncy elite blower motor not working

There is a fusible link for the blower motor. Check that. Don't know where it is. Look up the wiring diagram at autozone.com. Also check the fuse in the fuse box. Could just be that.
