Detailed Description

In Jeep Liberty applications, this actuator helps regulate how air is directed and mixed through the HVAC system, supporting consistent cabin temperature control. This part cross-references Dayco 73151 for the same application.

Use this actuator when servicing a Jeep Liberty with air door movement concerns and you need a replacement that matches the original linkage style, mounting ear count, and terminal configuration. The Four Seasons 73151 is listed for 2005 Jeep Liberty from 6/12/04 and 2006-2007 Jeep Liberty, making it a focused option for those model years.

Common Issues This Part May Resolve
