The blend door actuator on a 2017 Kia Sportage is a small plastic gear motor behind the dashboard that directs hot or cold air into the cabin. When it fails you get a persistent clicking sound from the center console, temperature control that only blows one temperature regardless of dial position, or a complete loss of airflow direction. Replacing it with the correct part stops the noise and restores proper HVAC function without a dealer visit.

Whether you are tackling a DIY dash repair yourself or handing the job to a shop, finding the right 2017 kia sportage blend door actuator depends on matching the exact position, connector type, and spline pattern to your vehicle’s build date and trim level.
How To Choose The Best 2017 Kia Sportage Blend Door Actuator
The 2017 Kia Sportage uses a multi-zone HVAC system with separate actuators for temperature blend, mode direction, and air intake. Selecting the wrong part wastes time and requires pulling the dash again. Focus on the fitment verification method and the construction of the internal plastic gears rather than brand name alone.
Verify the correct position and OEM number first
The Sportage has at least four different actuators in the HVAC case — center temperature blend, driver temperature blend, mode, and air intake. The center blend actuator uses OEM 971621JAA0, the air intake actuator uses 971573T000, and the main mode actuator uses 971571JAA0. Check your failing unit’s part number before ordering. Inputting your VIN into the fitment tool is not enough because your specific trim may use a different connector or gear orientation.
Look for reinforced gear construction
The most common failure mode on Kia blend door actuators is stripped plastic gears driven by a small DC motor. Aftermarket units with nylon or polycarbonate gears bonded to metal shafts resist wear longer than pure sintered plastic gear sets. Dorman and premium aftermarket brands often reinforce the output gear to prevent the clicking failure from returning.
Confirm the connector pin count and shape
The 2017 Sportage uses both 5-pin and 7-pin connectors depending on the actuator position. A temperature blend actuator typically uses a 5-pin rectangular connector, while the mode actuator often uses a 7-pin connector. The physical shape of the connector housing also differs between Hyundai/Kia generations — visually match the plug shape to your original part.

In‑Depth Reviews
1. Dorman 604-329 HVAC Blend Door Actuator
The Dorman 604-329 is purpose-built as a direct replacement for the center temperature blend door actuator on the 2017 Kia Sportage. It matches the OEM 971621JAA0 part number and includes the correct 5-pin connector and spline orientation that fits the Sportage’s HVAC case without modification. The 3.87-ounce weight and 3.36×2.99×2.99-inch dimensions align closely with the factory unit, meaning you do not need to bend or shim the mounting bracket during installation.
Dorman reinforces the internal gear train to resist the stripping failure that plagues earlier Kia actuators. Owners report the plastic output gear uses a thicker tooth profile and a metal insert at the shaft interface, which reduces the likelihood of the clicking noise returning after 6 to 12 months. The unit is also tested for electrical burnout at the motor commutator, a common failure point when the actuator stalls against a stuck door.
For the 2017 Sportage owner who wants a single reliable replacement for the center blend position, this Dorman unit offers the best balance of fitment certainty and durability. It sits in the mid-range price tier and delivers OE-level performance without the dealer mark-up.
What works
- Direct fit to 971621JAA0 without adapter harness or bracket modification
- Reinforced internal gear reduces repeat clicking failure within 12 months
- Tested for stall and voltage surge protection at the factory level
What doesn’t
- Some examples arrive with the calibration tab not seated properly; manual rotation needed before install
- Does not include mounting screws — reuse original bolts
2. A-Premium APBDA0371 HVAC Heater Blend Door Actuator
The A-Premium APBDA0371 is a main mode actuator compatible with multiple Kia and Hyundai models, including the Sportage from 2010 to 2015. It cross-references to OEM 971571JAA0 and replaces Dorman 604-330. The mode actuator controls which vents the air flows through — defrost, panel, or floor. When this actuator fails, the dashboard vents may blow only one direction regardless of the mode dial setting.
A-Premium markets this unit specifically for noise reduction, using a damped motor mount and tighter gear lash tolerances than budget no-name alternatives. The 5.6-ounce weight is slightly heavier than stock, suggesting a beefier internal housing. The one-year unlimited-mileage guarantee provides basic warranty coverage for buyers who want reassurance against early failure.
Note the fitment window — the Sportage listing covers models built from April 29, 2010 onward, which includes the 2017 model year only if your specific trim uses the 971571JAA0 mode actuator rather than a different part. Verify your current actuator’s number before purchasing. This unit is best suited as a mode actuator replacement, not a temperature blend replacement.
What works
- Wide cross-vehicle compatibility allows reuse if you sell the car
- Noise-dampened motor mount reduces clicking during operation
- One-year warranty covers replacements for fitment errors or defects
What doesn’t
- Fitment to 2017 Sportage depends on exact build date and trim — verify with OEM number first
- Does not include calibration instructions in package; must self-calibrate after install
3. BIG TIGER PARTS 971573T000 OEM Air Intake Actuator
The BIG TIGER PARTS 971573T000 is a genuine OEM factory part sold in original retail packaging. This is the exact same actuator that ships on the Sportage assembly line for the air intake door, which controls whether the HVAC pulls outside air or recirculates cabin air. When this actuator fails, you may hear a clicking from behind the glove box and the recirculation button may flash or become unresponsive.
Because it is a factory Hyundai/Kia part, the connector shape, pin layout, spline count, and mounting tab orientation match 100 percent. The 4.2-ounce unit fits the air intake housing without any adapter or modification. OEM parts typically cost more than aftermarket equivalents — this unit sits in the premium price tier — but the trade-off is guaranteed first-try fitment and no guessing about internal plastic grade or gear strength.
For the Sportage owner who values zero-fitment-risk above all else, the OEM 971573T000 eliminates the most common headache: ordering the wrong actuator because the online fitment tool showed compatibility but the physical connector does not match. This is the right choice for the air intake position specifically.
What works
- Factory-fresh part with exact OEM connector, spline, and bracket geometry
- No calibration routine needed — plug-and-play with factory HVAC module
- Highest durability against continuous recirculation cycling through seasons
What doesn’t
- Premium price relative to aftermarket equivalents that meet the same spec
- Limited to the air intake position only; not interchangeable with temperature or mode actuators
4. TCFWED 81310-D9010 Door Lock Latch Actuator
The TCFWED 81310-D9010 is a door lock latch assembly with an integrated actuator for the front driver side of the 2017-2022 Kia Sportage. This is not a blend door actuator — it controls the mechanical locking and unlocking of the driver door. The 7-pin plug connects to the body wiring harness and the unit replaces OEM 81310-D9010. If your driver door does not lock or unlock with the remote or interior switch, this latch assembly is the likely culprit.
Construction uses new high-quality raw materials with steel internal linkages rather than all-plastic components. The 11.36-ounce weight reflects the metal latch mechanism, which is heavier than a plastic HVAC actuator. The one-year unlimited-mileage warranty covers manufacturing defects, and the seller provides installation steps in the listing for DIY replacement.
For owners with a 2017 Sportage experiencing a door lock problem rather than an HVAC temperature issue, this is the correct part to consider. It does not replace a blend door actuator — it solves a completely different electrical-mechanical failure mode. Ensure your symptom is the door not responding to lock/unlock commands before purchasing.
What works
- Direct replacement for driver side door lock assembly — no wiring splicing needed
- Steel linkages inside the latch provide longer mechanical life than plastic-only designs
- Includes detailed installation steps for DIY replacement
What doesn’t
- Not a blend door actuator — will not fix HVAC temperature or mode problems
- Higher weight requires careful handling during install to avoid damaging door panel clips
5. Parts Port 81420-D9000 Power Door Lock Actuator w/Latch
The Parts Port 81420-D9000 is a rear right door lock latch assembly with an integrated actuator for the 2017-2022 Kia Sportage. It replaces OEM 81420-D9000 and handles the mechanical locking and unlocking of the passenger rear door. At a budget-friendly price point, this unit offers a low-cost solution for a rear door that fails to lock with the central system.
The 1.5-pound weight is heavier than most door actuators because it includes the full latch mechanism, not just the motor. The included components are limited to the latch assembly itself — you reuse the original mounting bolts and door panel clips. Parts Port provides a one-year warranty on replacement of the part only, so the labor to reinstall is the owner’s responsibility.
This unit serves a specific door lock symptom, not an HVAC blend door issue. If your 2017 Sportage rear right door does not lock or unlock with the key fob or central lock switch, this is a functional and cost-effective fix. For temperature blend problems in the center console, look at the Dorman 604-329 instead.
What works
- Full latch and actuator assembly simplifies DIY replacement versus swapping just the motor
- Lightest price point makes it an easy first try for rear door lock diagnosis
- Direct OEM number cross-reference reduces fitment guesswork
What doesn’t
- Limited to rear right position only — not interchangeable with other doors
- Warranty covers part replacement only; no coverage for labor or shipping costs
Hardware & Specs Guide
Actuator Position Mapping
The 2017 Sportage HVAC case houses separate actuators for the center temperature blend (part 971621JAA0), driver temperature blend, mode direction (971571JAA0), and air intake door (971573T000). Verify which position is faulty before ordering — the center blend actuator controls the mix of hot and cold air entering the cabin and is the most common failure point. The air intake actuator is located behind the glove box and uses a different 5-pin connector orientation.
Internal Gear Construction
Most Kia blend door actuator failures originate from a stripped plastic output gear. OEM gears are sintered nylon, which wears under stall loads. Premium aftermarket units like the Dorman 604-329 use a thicker tooth profile with a metal bushing at the drive shaft interface. Door lock actuators operate with heavier steel linkage assemblies and do not suffer from the same gear failure mode — their failures typically come from a worn DC motor brush or corroded connector pins.
