Detailed Product Information

Four Seasons 73712 is an HVAC mode door actuator engineered for consistent operation in the vehicle’s air distribution system. The cam linkage design works with the mode door mechanism to change vent position, while the 5-pin terminal layout supports the actuator’s electrical control function. This part is listed for 2014-2024 Mitsubishi Mirage and 2017-2024 Mitsubishi Mirage G4 applications, making it a focused replacement for common Mitsubishi Mirage HVAC mode door actuator service needs. If your Mitsubishi Mirage or Mirage G4 is stuck on one vent setting, this actuator is the type of component used to restore normal mode selection.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Airflow stuck on defrost, dash, or floor vents
• Inconsistent vent mode changes from the climate controls
• Clicking or binding from the HVAC mode door area
• Loss of proper cabin air direction in Mitsubishi Mirage and Mirage G4 models
• Faulty actuator response in the HVAC air distribution system

Installation Notes and Tips

Verify the connector style, mounting ear layout, and cam linkage match the original actuator before installation. Confirm the vehicle’s year and model against the listed fitment for 2014-2024 Mitsubishi Mirage and 2017-2024 Mitsubishi Mirage G4. After installation, cycle the HVAC controls through each mode setting to confirm the door moves correctly and air is routed to the selected outlets.
