J.C. Whitney RN19230001 HVAC Heater Blend Door Actuator 2-Pin Manual Temperature Control

The J.C. Whitney RN19230001 is an OEM-replacement HVAC heater blend door actuator designed for the Nissan Sentra (2013–2019) equipped with manual temperature control. This actuator regulates the blend door position inside the HVAC housing, controlling the mix of hot and cold air to deliver precise cabin temperatures. It replaces OEM part number 277303RA0A (also cross-references as 73591).

Key Features:

• Direct OEM replacement — fits and functions like the original factory part
• 2-pin terminal connector for straightforward plug-and-play installation
• Compatible with manual temperature control (red/blue dial) systems only — not compatible with Automatic Temperature Control (ATC) systems
• Restores proper HVAC airflow and temperature blending function
• Durable construction designed to meet original equipment specifications

OEM / Cross-Reference Part Numbers:

• OEM: 277303RA0A
• Cross-Reference: 73591

This blend door actuator is an ideal solution for Sentra owners experiencing stuck airflow, incorrect cabin temperature, or a clicking/grinding noise from behind the dashboard — common symptoms of a failed actuator. Verify your vehicle's temperature control type (manual vs. automatic) before installation.
