Front Right Hand Window Regulator (China-Localized) for Tesla Model 3 (2017-2023) | 1616443-99-A

Bring Back Effortless Window Control to Your Model 3

Built for Precision and Durability

• Smooth, Stutter-Free Movement: At its core is a high-torque DC motor paired with precision-machined gears and a reinforced cable system. Together, they work to move the window glass evenly—no jerks, lags, or sudden stops—whether you’re cracking it open for fresh air or closing it tight against rain. The components are calibrated to minimize friction, so even after years of use, the window glides as smoothly as on day one.
• Quiet Operation: Unlike generic regulators that squeak or grind, this China-localized part features noise-dampening design elements. Rubber bushings isolate vibrations, and lubricated linkages reduce sound, keeping window adjustments nearly silent—preserving the peaceful cabin environment Tesla is known for.
• Weather-Resistant Construction: Designed to withstand China’s diverse climates, from humid summers in the south to freezing winters in the north. The metal components are treated with anti-corrosion coatings, and the plastic parts resist warping from extreme temperatures, ensuring longevity even in harsh conditions.

Why It’s Optimized for China-Market Model 3s

• Road-Tested for Local Conditions: This regulator has undergone extensive testing on China’s unique road surfaces, from busy urban streets to rough rural roads. Its reinforced mounting points and flexible cable system better absorb vibrations from uneven terrain, reducing wear and tear.
• Alignment with China-Spec Doors: Model 3s sold in China feature subtle differences in door panel dimensions and electrical harness layouts. This regulator’s mounting holes and 12V connector are precision-matched to these specs, ensuring a plug-and-play fit without modifications.
• Compliance with Local Standards: It meets China’s automotive safety and durability regulations, including rigorous tests for temperature resistance (-40°C to 85°C) and cycle endurance (over 10,000 open/close cycles without failure).

Signs Your Regulator Needs Replacement

• Sluggish or Erratic Movement: The window takes longer to open/close, pauses midway, or moves unevenly—often due to a worn motor or frayed cables.
• Loud Noises: Grinding, squeaking, or rattling during operation signals damaged gears or loose components. Ignoring this can lead to complete failure.
• Window Drooping: If the glass sags or tilts when open, it’s likely the regulator’s support brackets are bent or broken.
• Stuck in Place: A window that won’t move at all (even when you hear the motor running) usually means a snapped cable or seized mechanism.

Installation & Calibration Tips

• Professional Installation Recommended: While DIY-savvy owners can attempt it, the process involves removing the door panel, disconnecting electrical harnesses, and securing delicate components. A certified technician will ensure proper alignment, preventing leaks or glass damage.
• Calibration is Key: After installation, follow Tesla’s built-in calibration steps to sync the regulator with the window:
  1. Close the front right door and sit in the driver’s seat.
  2. Use the driver’s side window switch to fully raise the front right window until it stops.
  3. Lower it completely, then raise it again to the top. This resets the regulator’s position sensors, ensuring proper operation (e.g., the window won’t hit the door frame when closing).
