GM GENUINE PARTS HVAC Temperature Valve Actuator 15-74347 (22808876) OE-fit Blend Door Motor, Direct Replacement

This GM-recommended temperature valve actuator is a direct replacement for the original factory unit on compatible General Motors vehicles. Designed and manufactured to GM Original Equipment specifications, it restores proper operation to the HVAC blend-door system so your vehicle can deliver the intended mix of heated or cooled air to the cabin vents. The actuator connects to the vehicle’s climate control command and translates electrical signals into precise mechanical motion.

How does this actuator restore HVAC temperature control?

When the climate control system sends a signal, the actuator converts that input into movement that opens or closes the blend door. That motion changes the route of air through the heater core or bypass path, adjusting the temperature of the air reaching the vents. Replacing a worn or failing actuator returns accurate, repeatable door positioning and reduces inconsistent cabin temperatures.

• Direct-fit GM OE replacement for proper mechanical and electrical compatibility
• Restores precise blend-door movement for predictable temperature changes
• Reduces HVAC noise and erratic door behavior caused by failing actuators

What are the key features and build standards of this part?

This actuator is built to GM-recommended standards for fit, function, and durability. Materials and tolerances match the original specification so the unit integrates with existing linkages and mounts without modification. It includes the necessary electrical connector profiles for a plug-and-play replacement.

• Manufactured to GM OE specifications for fit, form, and function
• Electrical interface matched to factory wiring harnesses
• Durable motor and gear components for long service life

Will this part fit my vehicle and what should I check before buying?

GM Genuine Parts 15-74347 is intended as a direct replacement for specific GM applications; verify the OEM number (22808876) against your vehicle’s parts catalog or VIN cross-reference. Check compatibility charts or contact GM parts support to confirm fitment for model year and trim variations, since some international variants can have different components.

• Confirm part number 15-74347 / 22808876 matches your vehicle
• Compare connector type and mounting points to your original actuator
• Review fitment notes for international product differences if applicable

How difficult is installation and what should installers expect?

Installation complexity ranges from simple to moderate depending on dash trim access for your vehicle. The actuator typically mounts to the HVAC housing with a few fasteners and a single electrical connector. Basic hand tools and light disassembly of panels are usually all that’s required; consult a service manual for vehicle-specific procedures.

• Expect to remove minimal dash trim for access in most models
• Plug-and-play electrical connection simplifies replacement
• Follow manufacturer torque and calibration steps if required

Who is this for: GM Genuine Parts 15-74347 (22808876) is aimed at vehicle owners, DIY mechanics, and professional technicians who need an OEM-grade replacement for a failing HVAC temperature valve actuator. Choose this part when you want factory-equivalent fit and reliable operation to restore proper cabin temperature control in compatible GM models.
