J.C. Whitney RA19300005 HVAC Air Inlet Door Actuator 5-Pin OEM Replacement 79240-TZ5-A41

The J.C. Whitney RA19300005 is a direct-fit OEM replacement HVAC air inlet door actuator designed to restore proper fresh air and recirculation control to your vehicle's climate system. This actuator replaces Honda/Acura OEM part number 79240-TZ5-A41 and features a 5-pin male terminal connector for a plug-and-play installation with no wiring modifications required.

The air inlet door actuator (also known as a recirculation door actuator or fresh air/recirculation blend actuator) is a small electric motor assembly mounted inside the HVAC housing. It controls the position of the inlet door that switches the system between recirculating cabin air and drawing in fresh outside air. A failed actuator can result in loss of recirculation mode, clicking or grinding noises from behind the dashboard, or a stuck inlet door.

Key Features:

• Direct OEM replacement — cross-references Honda/Acura part 79240-TZ5-A41
• 5-pin male terminal connector for direct plug-in installation
• Controls HVAC air inlet door (fresh air vs. recirculation mode)
• Restores proper automatic climate control and manual A/C functionality
• Built to OEM specifications for reliable, long-term performance
• No cutting, splicing, or adapter harnesses required

This actuator is engineered as a precise OEM-equivalent replacement, ensuring your climate control system operates exactly as intended from the factory. Straightforward installation makes this an ideal DIY repair for restoring full HVAC function.
