Detailed Description

Four Seasons 73097 is an HVAC mode door actuator used in the auxiliary position on 2001-2005 Pontiac Montana and 2001-2004 Oldsmobile Silhouette models. It controls the movement of the HVAC air door so the system can direct airflow through the proper vents and outlets. This part cross-references A27397 and 604199 for the same application.

When the actuator wears out or loses calibration, the HVAC system may stop responding correctly to mode changes. Replacing the faulty unit with the correct Four Seasons 73097 air door actuator helps restore commanded airflow control in the vehicle’s heating and air conditioning system.

Common Issues This Part May Resolve

  • Airflow stuck on one vent setting
  • No response when switching HVAC modes
  • Clicking or repeated actuator movement behind the dash
  • Improper air distribution between defrost, panel, and floor outlets
  • Loss of auxiliary HVAC door control

Installation Notes and Tips

Verify the connector style, mounting ear layout, and door linkage before installation. This part is listed for the auxiliary position only, so confirm the vehicle’s HVAC door location matches the application before replacing the actuator.
