To replace the heater fan in a 1998 Buick Regal, first disconnect the negative battery cable to ensure safety. Remove the dashboard panel and the HVAC control knobs to access the blower motor. Unscrew the blower motor assembly from its housing, disconnect the wiring harness, and replace it with the new fan. Finally, reassemble the components in reverse order and reconnect the battery.
