Bring your climate controls back to life with the Dorman blend door actuator 604-106, a direct-fit HVAC Heater Blend Door Actuator that drives the air doors so your system can shift between heat, cool, and defrost. This small electric motor positions the blend door inside the HVAC case; if it fails, you may notice a temperature that won't change, air routed to the wrong vents, or clicking behind the dash — if the actuator is the cause, this replaces it.
The catalog lists this actuator in MAIN, AUXILIARY, RIGHT MAIN, UPPER MAIN, LOWER MAIN, and LEFT MAIN positions, so match it to the actuator you need.
- Direct replacement: engineered to install like the original air door actuator and restore proper HVAC operation on the listed applications.
- Position specific: vehicles often use several different HVAC door actuators — check this part's application notes to confirm it matches the location and function of the one you're replacing.
- Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable, long service life.
- Trustworthy quality: backed by a team of experts and engineers in the United States and more than a century of experience.
