the quad driver module is a component of the ECM. you must replace ECM.
In a 1998 Buick Park Avenue, the dash lights and heater blower module are typically located under the dashboard on the driver's side. The heater blower motor is often found near the firewall, while the dash light dimmer switch can be located on the dashboard itself, near the headlight switch. For access, you may need to remove some panels or covers. Always consult the vehicle's service manual for specific details and diagrams.
