2017 Kia Cadenza Window Motor: Faults, Part Numbers & Replacement Guide
A complete reference for diagnosing and replacing the window motor in a 2017 Kia Cadenza, including crucial part numbers for each door.
- Each door on the 2017 Cadenza uses a unique, position-specific window motor; verify the part number before buying.
- A window that makes noise but doesn't move is likely a failed regulator, while a window that makes no noise is likely a failed motor, switch, or fuse.
- You can test the motor directly by removing the door panel and applying 12V power to its electrical connector.
- A used OEM motor is a reliable and cost-effective option, provided you verify the part number and inspect the connector for corrosion.
Understanding the 2017 Cadenza Window Motor
The window motor is a common failure point in many vehicles. In the 2017 Kia Cadenza, the motor is a distinct component from the window regulator (the track and cable assembly that holds the glass). This is important because you can often replace just the failed motor without needing to buy the entire, more expensive regulator assembly. This guide focuses specifically on the window motor for all four doors of the 2017 Cadenza.
Compatibility Warning: The initial information provided about this part being specific to the 3.3L engine is correct only because the 3.3L V6 was the standard engine for the 2017 Cadenza in the North American market. The most critical factor is ensuring you purchase the motor for the correct door, as they are not interchangeable.
Window Motor vs. Window Regulator Failures
It's common to confuse a bad window motor with a bad window regulator. While no specific recalls or Technical Service Bulletins (TSBs) were found for the 2017 Cadenza window motor, related Kia models from the same era (like the 2017 Optima and Sportage) have known issues with window regulator failures. This is often due to a weak plastic gear inside the regulator assembly breaking. If you hear the motor whirring or clicking but the window doesn't move or moves erratically, the problem is likely the regulator, not the motor. If you hear nothing, or only a faint hum, the motor is the more likely culprit.
Symptoms of a Failing Window Motor
A failing window motor typically gives several warning signs. Diagnosing the issue correctly can save you from replacing the wrong part.
- Slow or Sluggish Operation: The window moves up and down much slower than it used to. This indicates the motor is wearing out and losing power.
- No Movement, No Sound: When you press the switch, nothing happens. There is no clicking, whirring, or humming from inside the door. This often points to a dead motor, a bad switch, or a blown fuse.
- Intermittent Function: The window works sometimes but not others. This can be caused by a developing dead spot in the motor's internal windings or a loose electrical connection.
- Window Moves in Only One Direction: The window will go down but not up, or vice-versa. This can indicate an internal failure within the motor itself.
- Dimming Lights: If you press the window switch and the dashboard or headlights dim slightly, but the window doesn't move, it means power is reaching the motor, but the motor is seized and unable to turn.
- Burning Smell: A distinct electrical burning smell from the door area when using the switch suggests the motor has shorted out or severely overheated.
2017 Kia Cadenza Window Motor Part Numbers
Using the correct part number is essential. Each door on the Cadenza uses a different window motor. Verify the position you need before ordering.
| Position | OEM Part Number | Common Price (New OEM) |
|---|---|---|
| Front Right (Passenger Side) | 82460-F6000 / 82460F6000 | $200 - $210 |
| Front Left (Driver Side) | 82450-F6000 / 82450F6000 | $190 - $200 |
| Rear Right (Passenger Side) | 83460-F6000 / 83460F6000 | $85 - $95 |
| Rear Left (Driver Side) | 83450-F6000 / 83450F6000 | $85 - $95 |
Diagnosing the Problem: A Step-by-Step Guide
- Check the Fuses: Before taking the door apart, check the fuse box for any blown fuses related to the power windows. This is the simplest and most common fix.
- Test the Switch: Try operating the window from both the driver's master switch and the switch on the affected door. If it works with one switch but not the other, the problem is likely the switch itself, not the motor.
- Listen for Motor Noise: With the car on, have a helper press the switch while you listen closely to the inside of the door panel. If you hear a humming or whirring sound, the motor is receiving power. If the window isn't moving, the regulator is likely broken. If you hear nothing, the motor or wiring is the likely issue.
- Test for Power at the Motor: This requires removing the door panel. Unplug the electrical connector from the window motor. Use a multimeter or a 12V test light to check for voltage at the connector when the switch is pressed. If you get a 12-volt reading, the switch and wiring are good, and the motor has failed. If there's no voltage, the problem lies in the wiring or the switch.
Pro Tip: You can test a motor directly by applying 12V power from the car battery or a power probe to its terminals. If the motor spins, it's good. Reverse the polarity to make it spin in the opposite direction.
Buying a Used 2017 Cadenza Window Motor
A used OEM window motor is an excellent, cost-effective alternative to an expensive new part. Since these motors are not a high-wear item on the Cadenza, a low-mileage used part can provide years of reliable service. Here's what to look for:
- Verify the Part Number: This is the most important step. Use the table above to match the part number exactly to the door you are repairing. An honest seller will provide clear pictures of the part number sticker.
- Inspect the Electrical Connector: Look at photos of the connector pins. They should be clean and free of any green or white corrosion, which indicates water damage.
- Check the Gear: The small gear on the motor should have clean, sharp teeth. Avoid any motors with visible damage or excessive grease that might be hiding wear.
- Understand What You're Buying: Confirm that the listing is for the motor only. The part you are buying should not include the large metal regulator assembly, cables, or mounting plate.
- Why Used OEM is a Good Choice: Original Equipment Manufacturer (OEM) parts are built to Kia's exact specifications for fit, electrical draw, and durability. A used OEM motor is often a better choice than a cheap aftermarket part, which may have a different rotational speed, draw more power, or use lower-quality internal components.
Cost of Replacement
Replacing a window motor involves both the part cost and labor. While a DIY replacement is very feasible, here is a breakdown of what you can expect to pay.
| Item | Estimated Cost | Notes |
|---|---|---|
| New OEM Motor | $85 - $210 | Price varies significantly by door position. |
| Used OEM Motor | $50 - $130 | Based on online marketplace listings. |
| New Aftermarket Motor | $150 - $300+ | Direct-fit options may be limited; this is a general estimate. |
| Shop Labor | $98 - $145 | Typically 1-1.5 hours of labor to remove the door panel and replace the motor. |
| Total Professional Replacement | $387 - $433 | Using a new OEM part at a repair shop. |
Frequently Asked Questions (FAQ)
Is it difficult to replace a window motor myself?
For a DIY mechanic with basic tools, this is a moderately difficult job, rated about a 3 out of 5. The main challenge is removing the interior door panel without breaking any of the plastic retaining clips. It's recommended to use a set of plastic trim removal tools. Once the panel is off, the motor is typically held on by just a few bolts.
Do I need to reset or program the window after replacing the motor?
For the 2017 Cadenza, the standard window motors (without auto up/down) generally do not require a reset procedure. You simply install the new motor, connect it, and test the operation. If your vehicle has an 'auto up/down' feature, a reset procedure (running the window fully up and down and holding the switch) might be necessary, but this is more common on the regulator/motor assembly as a whole.
Can a bad window motor drain my battery?
It is possible, but rare. If the motor's internal circuitry shorts out in a way that creates a constant electrical draw, it could drain the battery over time. More commonly, a stuck switch could continuously send power to the motor, causing it to overheat and potentially drain the battery, but this would also likely blow a fuse first.
My window dropped into the door. Is that the motor?
No, if the window glass has fallen down inside the door, the problem is almost certainly a broken window regulator, not the motor. This usually happens when the cables snap or the plastic guides break. You will need to replace the window regulator assembly.
