FINDAUTO Power Window Regulator for Kia Sorento Rear Left 2016-2020 — OE-fit, Durable Bracket

FINDAUTO's power window regulator replaces the rear left (driver-side) mechanism for 2016–2020 Kia Sorento models, delivering smooth, quiet glass movement (motor not included).

If the rear left window on your Kia Sorento sticks, wobbles, or won't move up and down reliably, a worn regulator is a common cause. This FINDAUTO replacement is built to match original equipment standards and has been cycled repeatedly in real vehicle doors to verify durability and consistent performance. It installs where the factory unit sat and uses a robust bracket to lift and lower the glass without excessive play, noise, or vibration.

What exact vehicles and door position does this part fit?

This regulator is engineered specifically for Kia Sorento model years 2016, 2017, 2018, 2019, and 2020, designed for the rear left (driver-side) door. Confirming the part numbers and door orientation before ordering helps prevent returns or fitment problems.

• Compatible years: 2016–2020 Kia Sorento
• Location: Rear left (driver-side) door
• Reference numbers: 83471C5000 and 83471C6000 for cross-checking
• Includes regulator assembly only — motor is not included

How does the FINDAUTO regulator improve window operation?

The assembly uses a reinforced bracket and precision slides to guide the glass smoothly along its track, reducing rattle and resistance. It’s built to OE tolerances so the window moves quietly and without binding when installed properly.

• Durable bracket material resists bending under load
• Smooth sliding action reduces noise and vibration
• OE-style fit minimizes alignment issues during installation
• Extensive cycling tests simulate real-world use for reliability

What should I know about installation and compatibility?

Installation follows standard door panel removal and bolt replacement procedures used for most Sorento rear door regulators. Since the motor is not supplied, reuse your existing motor or order a matching motor if needed. Double-check fit by matching the reference numbers and verifying left/rear door orientation.

• Replace through the rear left door access after removing the door panel
• Connect existing motor (motor not included) or fit a compatible motor separately
• Torque fasteners to factory specifications for secure mounting
• Test window travel after installation to confirm alignment and smoothness

How durable and reliable is this replacement part?

FINDAUTO manufactures this regulator to meet OE standards and cycles assemblies in real-door setups to confirm longevity. The reinforced bracket and quality components are selected to resist common failure modes like bending, slipping, and noisy operation.

• Built to OEM-equivalent specifications for part fit and function
• Tested by repeated cycles in vehicle doors to help ensure long life
• Designed to limit shaking or off-track movement of the glass
• Backed by seller support — contact FINDAUTO with fitment questions

Who is this for: This FINDAUTO rear left power window regulator suits do-it-yourself mechanics, independent repair shops, and Sorento owners who need a reliable, OE-style replacement for a failing rear left (driver-side) window mechanism for 2016–2020 Kia Sorento vehicles. It’s ideal if you have a working motor to reuse or plan to install a compatible motor separately. Always verify your vehicle year, door side, and reference numbers (83471C5000 / 83471C6000) before purchase; contact FINDAUTO for help if you’re unsure.
