Detailed Description

This HVAC blend door actuator is used to control air temperature by moving the blend door inside the heater and air conditioning case. Dorman 604-011 is a fitment-based replacement for select 1998-2004 Chrysler Concorde, 1998-2004 Chrysler Intrepid, 1998-2004 Dodge Intrepid, 1999-2004 Chrysler 300M, and 1999-2001 Chrysler LHS applications in the main blend position. It is a practical replacement for vehicles experiencing inconsistent cabin temperature control, and it cross-references Standard Ignition ADR4307 for the same application.

What It Helps Fix

• Incorrect cabin temperature output
• Temperature stuck on hot or cold
• HVAC blend door movement failure
• Loss of proper air mixing between heater and A/C modes
• Clicking or erratic actuator operation in the dash HVAC system

Installation Notes and Tips

Verify the vehicle year, make, model, and main blend position before ordering. This actuator is a rotary-style unit, so confirm the electrical connector and mounting style match the original part on your Chrysler 300M, Concorde, Intrepid, Dodge Intrepid, or LHS. Access is typically through the HVAC housing, so inspect the blend door and related linkage for binding or damage during replacement.
