Genuine 27732-3JC1A HVAC Air Mix Door Actuator Assembly

The Genuine 27732-3JC1A is an OEM HVAC Air Mix Door Actuator Assembly — also commonly referred to as a blend door actuator or temperature door actuator — designed as a direct factory replacement for Nissan and Infiniti vehicles.

What It Does:

The HVAC system in your vehicle mixes warm and cool air to reach the desired cabin temperature. This actuator is a small electric motor that controls the movement of the air mix (blend) door inside the HVAC housing, regulating the ratio of hot and cold airflow. Without a properly functioning actuator, the climate control system cannot accurately maintain temperature settings.

Key Features:

• Genuine OEM part — manufactured to factory specifications for guaranteed fit and function
• Also known as: Air Mix Actuator, Blend Door Actuator, HVAC Temperature Door Actuator
• Available for left and right positions depending on application
• Compatible with non-navigation HVAC systems (air mix, without navigation)
• Backed by the Nissan/Infiniti Parts & Accessories Limited Warranty
• Replaces part number 277323JC1A (no-dash alternate format)

Common Failure Symptoms:

• HVAC system stuck on one temperature regardless of settings
• Clicking or tapping noise from behind the dashboard
• Inconsistent or unresponsive cabin temperature control

Electrical burnout and internal gear failure are the most common causes of actuator failure. Replacing this component with a genuine OEM unit restores precise climate control performance.
