YAOPEI HVAC Heater Blend Door Actuator 2-Pack for GM Trucks SUVs (Replaces OE 604-106) — Durable OEM Fit

These two YAOPEI HVAC heater blend door actuators replace OE 604-106 to restore proper temperature and airflow control in compatible GM trucks and SUVs.

If your vehicle is producing uneven cabin temperatures, clicking noises from the dash, or vents that won't switch between heat and A/C, a worn blend door actuator is often the cause. This 2-piece set from YAOPEI is built to the original fit and function standards and fits a wide range of Chevrolet, GMC, Cadillac, Buick, Oldsmobile, Pontiac, Isuzu and Hummer models across late-1990s through mid-2010s model years.

How will replacing the blend door actuator affect cabin temperature control?

Installing a fresh actuator lets the HVAC system move the internal dampers precisely, so the climate controls actually correspond to the air that comes from the vents. Expect faster and smoother transition between hot and cold settings and accurate vent selection.

• Restores accurate hot/cold mixing and vent selection
• Stops intermittent or constant clicking from the dash
• Improves comfort on long drives and quick temperature changes

Which vehicles and part numbers does this 2-pack replace?

The set is compatible with many GM platforms and replaces common OEM numbers for straightforward swap-in replacement. Cross-references include OE 604-106 and several alternate part numbers used across brands and years.

• Replaces: 604-106, 52402588, 89018365, 15-72971, 16163982, 52402598, 52402612
• Fits: Silverado, Sierra, Suburban, Tahoe, Yukon, Escalade, Hummer H2, and more
• Coverage: Model years span late 1990s to mid-2010s depending on application

What are the construction and durability features of these actuators?

YAOPEI builds these actuators with reinforced plastic housings and upgraded internal circuitry for longer service life under heat and vibration. The motor and board are designed to resist corrosion and tolerate the thermal cycles inside an instrument panel.

• Durable plastic housing matched to OEM dimensions
• Robust motor and internal circuit board for heat and vibration resistance
• Manufactured to factory-style specifications for reliable operation

Is installation difficult and what comes in the package?

Installation is typically straightforward and can be completed with basic hand tools; many owners replace this actuator themselves. After physical installation, recalibration of the HVAC system may be needed to sync the new unit to your vehicle's control module.

• Package includes two blend door actuators (2 PCS)
• No specialty tools required for most installations
• Remember to recalibrate the HVAC system following replacement

Who is this for: This 2-pack is aimed at owners and DIY mechanics who drive GM full-size trucks and SUVs that exhibit temperature control faults, dash actuator noises, or faulty vent selection. It’s also useful for repair shops looking to stock a commonly failing HVAC component with broad vehicle coverage. If you want an OEM-fit replacement that restores proper airflow mixing and avoids repeated trips to the dealer, these YAOPEI actuators provide a practical, cost-effective solution.
