Specifications:

Part Number: 1500604-00-B

Position: Rear trunk/tailgate

Common Signs You May Need Replacement:

The trunk won’t latch properly

Trunk pops open unexpectedly

Vehicle displays trunk open warning

Clicking sound but no latch movement

• Trunk Won't Close: The latch hook fails to retract or grip the striker.
• False "Trunk Open" Alerts: The trunk is physically closed, but the car screen displays a warning, preventing the vehicle from locking or causing alarm triggers.
• Grinding Noises: Hearing clicking or grinding sounds during the closing process usually indicates stripped internal plastic gears.

• Model Y vs. Model 3: While part 1500604-00-B is often listed as universal, certain Model 3 production years may have slight bracket offsets. However, for the Model Y (2020–2023), this is the definitive standard part.
• Newer Versions: If your vehicle is a 2024+ refreshed model, visually compare your old unit first. This part is primarily designed for the 2020–2023 production cycle.

• Manual Release Cable: During installation, reconnect the original emergency manual release cable to the new actuator. If forgotten, you will have no way to open the trunk from the inside if the 12V battery dies.
• Corrosion Inspection: Model Y trunk seals can sometimes leak, allowing water to travel down the wiring harness into the connector. Before plugging in the new latch, check for green corrosion on the pins. Use electronic cleaner if necessary to prevent burning out the new motor.

• System Reset: After physical installation, the trunk movement logic might still be slightly off. You should enter Service Mode on the center screen, navigate to Closures, and run the Trunk/Liftgate Calibration. This allows the car's computer to learn the precise end-points of the new latch.
