AITKEN HVAC Blend Door Actuator for INFINITI Q50/Q60 — Left Side, OEM-Fit & 1-Year Warranty

The AITKEN Left Side Air Mix Blend Door Actuator precisely controls cabin temperature by moving the HVAC blend door to direct hot or cold air where you need it.

When your INFINITI Q50 (2014–2022) or Q60 (2015–2017) blows the wrong temperature or makes clicking noises behind the dash, the blend door actuator is often the culprit. This AITKEN replacement (reference numbers 27732-4GF0A / 27732-4GFOB / 27732-4GF0C) is designed to match OEM fit and function for left-side applications, tested on vehicle and backed by a one-year warranty. It targets the common faults drivers report—incorrect temperature control and repetitive clicking—while offering a durable, electrically reliable alternative to worn factory units.

How does this actuator restore correct cabin temperature?

The actuator repositions the air mix door that blends heated and cooled air before it reaches the cabin. By accurately moving to the commanded angle, it lets the HVAC system deliver the temperature you select instead of a fixed hot or cold output.

• Direct replacement for left-side air mix door on compatible INFINITI models
• Precise motor and gear movement for accurate temperature blending
• OEM-style electrical connector for plug-and-play installation

What symptoms indicate the actuator needs replacement?

Common signs include air that ignores your climate controls and audible clicking from behind the dash when you change temperature settings. These symptoms typically mean the internal gears or motor have failed and the blend door won’t move properly.

• Air remains too hot or too cold regardless of control input
• Repetitive clicking or grinding noises from the HVAC area
• Intermittent temperature changes or uneven airflow across vents
