A-NAFTULY Blend Door Actuator Kit for Chevy Impala 2004-2016 — 2x 604-108 & 1x 604-134, direct-fit HVAC replacement

This A-NAFTULY blend door actuator kit replaces the factory HVAC actuators (two 604-108 and one 604-134) to restore proper air flow and temperature control in compatible Chevy and GM vehicles.

If your vehicle is showing uneven cabin temperatures, strange clicking noises from the dash, or modes that won't change, worn blend door actuators are often the culprit. This three-piece replacement kit is designed as a direct-fit set for many GM models from the mid-2000s through 2016, matching original equipment fit and electrical connections so you can complete the repair with minimal fuss.

How will these actuators restore proper HVAC performance?

These actuators directly control the doors that route air and mix hot and cold into the cabin. Installing fresh actuators returns accurate door positioning so vents display the temperature and mode you select. They are built to the same mounting points and connector patterns as the originals for straightforward replacement.

• Replaces failed or noisy factory actuators 604-108 and 604-134
• Restores accurate driver and passenger temperature blending
• Smooth motor action reduces dash clicking and hunting

Is installation DIY-friendly and what aftercare is needed?

The actuators are engineered as direct replacements for the factory units, making them accessible for a one-person repair in most cases. Basic hand tools and removal of a few dash panels are normally required. After installation, the vehicle’s HVAC system should be recalibrated so the new actuators synchronize with the control module.
