why are the power locks not working on my Ford Mustang S650 (2024-Present)?

Solution

1. Preparation

• Gather tools and parts required.
• Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Replace Key Fob Battery (if applicable)

• Open the key fob using a small flat-head screwdriver.
• Remove the old battery and replace it with a new one, ensuring correct polarity.
• Reassemble the key fob and test the locks.

3. Inspect and Replace Fuses

• Locate the fuse box (typically under the dashboard or in the engine compartment).
• Remove the cover and identify the power lock fuse.
• Use a fuse puller to remove the fuse and inspect it for continuity.
• Replace with a new fuse of the same amperage if blown.

4. Test Power Lock Switch

• Remove the switch panel using a trim removal tool.
• Disconnect the wiring harness from the switch.
• Use a multimeter to test for continuity across the switch terminals.
• If faulty, replace the power lock switch with a new unit.

5. Inspect Wiring and Connectors

• Visually inspect the wiring harness leading to the door lock actuator for any signs of wear or damage.
• Ensure all connectors are securely attached.
• Repair or replace any damaged wiring or connectors as necessary.

6. Test Power Lock Actuators

• If the above steps do not resolve the issue, test the door lock actuators.
• Disconnect the actuator from the door and connect it directly to a power source to check functionality.
• Replace any faulty actuators.
