Hi, I'll try to explain the same thing with my car.
after replacing heater core I'd get the same problem coz they removed half of the cabin inside. they simply forgot to put down vacuum hoses
under a gear lever.after all was done properly they recommended to replace that unit asap. you've got some bad vacuum connections somewhere

Under the rear seat, two park brake relays(A and B). Remove and reinsert them to wipe the external contacts clean.

Unlike your car, the '99 uses an electronic solenoid release.
