7 Best Chevy Impala Blend Door Actuator | Fixes the Clicking

The single actuator that comes with a warranty as long as you own the car.

Getting a clicking noise from behind your dash does not have to mean dozens of future replacements. AA Ignition builds this part with a redesigned housing that uses improved plastic molding and internal circuitry — fixes meant to outlast the factory piece. It covers the 2004-2014 Impala model years and replaces part numbers 1573517, 1574122, 15844096, and 22754988, so it is a direct swap for your 2007 car.

Owners mention it fits perfectly and solves the clicking issue immediately. One owner noted that the actuator “seemed well constructed” but failed after two years of light use — a reminder that even a good aftermarket part does not always match the lifetime claim on paper. Still, the lifetime warranty means a free replacement ships out if yours ever quits, which beats paying for a new one down the road.

Unlike the multi-packs below that give you spares, this is a single unit. If you suspect a second actuator is failing, you might want a two-pack instead. But for a direct one-and-done swap with the strongest safety net, this is the pick.

A two-pack built from corrosion-resistant PP Plus GF material for high-mileage cars.

YHTAUTO chose a reinforced plastic called PP Plus GF (polypropylene with glass fiber) specifically because it resists corrosion and holds up to wear better than standard plastic. That matters in a 2007 Impala that has seen salt, moisture, and years of temperature cycling. The set replaces parts for both the main temperature and recirculation (air inlet) positions on the passenger side, which is exactly where the famous clicking noise lives.

One owner with a 2010 Impala documented a 1.5-hour install job that saved “a couple hundred dollars” compared to a shop visit. Another reviewer who has owned a 2013 Impala for five years said he has “gone through at least six or eight of these” from different brands and called YHTAUTO “the best actuator replacements yet.” That kind of repetition gives weight to the material upgrade.

The trade-off is that the price sits above entry-level two-packs, though still well short of dealer rates. If your car already has one clicking actuator, the second unit in the box lets you replace the partner actuator before it fails.

A solid single actuator that directly crosses to multiple OEM numbers including 604-108 and 15844096.

A-Premium markets this as a fit for the main temperature, mode, and air inlet positions on the passenger side, giving you flexibility if you are not sure which slot is bad. At 12.8 ounces it feels slightly heavier than the budget two-packs, which usually weigh around 8 ounces each. The extra weight often comes from a thicker plastic housing and a larger internal circuit board — both signs of a part built to handle more abuse than the bare-minimum replacements.

Reviewers on 2006 Monte Carlos and 2004-2008 Malibus confirm the fit works perfectly across the GM W-body platform. The one-year unlimited-mileage guarantee matches what A-Premium offers across its catalog, so if the gear strips inside that window, you get a fresh unit. A couple of buyers noted the install is “a b**** to get to” but that is the cramped Impala footwell, not the part’s fault. Unlike the YHTAUTO two-pack above, this is a single unit, so plan to buy two if you are tackling both the temperature and recirculation actuators at once.

Two actuators with an 18-month warranty for roughly the price of one premium single.

If you are doing the job yourself, having a spare actuator in the glove box is cheap insurance. A-NAFTULY sends two units made from ABS plastic (acrylonitrile butadiene styrene — a tough engineering thermoplastic that resists cracking). They cross to part numbers 604-108, 1573517, and 15844096, which are the exact numbers printed on the 2007 Impala’s factory unit.

A buyer with a 2008 Impala reported that the swap “got rid of the hvac clicking noises” immediately — the exact symptom you are chasing. Another owner on a 2010 Impala replaced one actuator and then a second one went out, so the extra piece in the box was already waiting. The 18-month warranty is six months longer than the typical one-year coverage most competitors offer, which gives a bit more breathing room if the first unit fails early.

Because these are ABS rather than the glass-filled plastic of the YHTAUTO set, they are slightly more prone to gear wear over very long periods. For most owners, though, ABS is the same material GM used in the original, so it is a direct quality match.

A two-pack that advertises heavier-duty gears specifically to outlast the factory part.

The RLP set targets the Impala’s weak spot head-on: the plastic gears inside the actuator that strip out and cause that frantic clicking. RLP claims motors designed for “heavier duty and higher strength gears” inside a durable plastic housing. At 0.24 kilograms (about 8.5 ounces per pair), the weight is in the normal range for a two-pack, but the focus on gear strength is what stands out. The set replaces the same 604-108 and 1573517 numbers and fits the 2004-2013 Impala plus the 2014-2016 Impala Limited.

Customers note it “works flawlessly on 2010 Chevy Impala LT” and notes that the plastic gears on the originals wear out — one owner said he “replaced 3 actuators twice” before trying these. The rearmost actuator behind the glove box is the easiest reach, but the air inlet position is harder with its tight bolt access. The 12-month warranty covers you for a year against a defect.

If you compare this to the A-NAFTULY two-pack above, both offer two units at a similar price. RLP leans harder on the “stronger gears” claim, while A-NAFTULY offers six extra months of coverage. Pick based on whether you value gear material over warranty length.

The cheapest two-pack that still gets the job done without fuss.

At 8.1 ounces for the pair, these are light units that rely on a solid plastic housing and high-tech internal circuit boards to resist electrical burnout. They cross to part numbers 604-108 and 1573517 and fit the Impala 2004-2013 plus the Impala Limited up to 2016. The price per actuator is the lowest in this lineup, making it the obvious pick if you are on a tight budget and just need the clicking to stop.

A buyer with a 2008 Impala said it was an “easy DIY install” and a “perfect fit for glove compartment side,” though he noted that no programming instructions come in the box — you will need to look up an online video for recalibration. Another owner said the parts are “prone to breaking” and that a local shop had three fail on his car, but he bought the bulk two-pack anyway because of the price. That split opinion is the reality at this price tier: the part works for many, but the QC is not as tight as the premium picks above.

One box with all three actuators so you never touch the dash again.

VCAUTO bundles the air inlet actuator, the mode actuator, and the temperature actuator into a single kit. If you are already pulling the glove box and the lower dash panel, replacing all three at once means you fix the current clicking and prevent the next one before it starts. The kit weighs 13.1 ounces total and includes a one-year warranty. It fits the 2004-2013 Impala, the Impala Limited up to 2016, plus the Corvette, Malibu, and other GM models.

The catch shows up in the reviews. Several buyers reported receiving defective units: one said “all 3 replacement actuators were defective” and the fix ended up costing more after extra trips. Another called the kit “absolute garbage” because none of the three worked. A single good review noted “they work great” but the failure rate in the feedback is the highest in this lineup. At this price, you are gambling on QC rather than paying for consistent quality.

Compared to buying two YHTAUTO units (which cover the two most common failure points) for a similar total cost, the VCAUTO kit gives you the third actuator for the air inlet — a position that fails less often. If you are unlucky, you might be buying the kit just to get one good unit out of three.
