1. The Trunk Release Button:
* Interior Release Button: Try the button inside the car. If it doesn't work, the problem might be with the button itself, its wiring, or the switch mechanism.
* Key Release: If your car has a key-operated trunk release, try that. A malfunctioning key cylinder or linkage is possible.
* Remote Release (if equipped): Check the remote's battery and ensure the remote is properly programmed.
2. The Trunk Latch Mechanism Itself:
* Cable/Rod Disconnection: The interior release button activates a cable or rod that connects to the latch mechanism. This cable or rod may have become disconnected or broken. You'll likely need to access the mechanism to check this (often involves removing interior trim).
* Latch Malfunction: The latch itself may be jammed, broken, or worn out. This is common over time due to rust or wear and tear. Again, you'll probably need to access the latch mechanism to inspect it.
* Actuator (for power trunk release): If you have a power trunk release, the actuator motor may have failed.
3. Wiring:
* Broken Wires: Check the wiring harness running to the trunk release switch and latch. Look for any broken, frayed, or corroded wires. This is especially important if the interior release and key release don't work.
4. Stuck or Frozen Latch:
* Debris: Sometimes, debris or ice can jam the latch mechanism. Try lubricating the latch mechanism with WD-40 (temporarily), or compressed air to blow out any debris. Note: WD-40 is a temporary fix - proper lubrication is best.
How to Access the Latch Mechanism:
This varies depending on the specific model of your 2000 Ford Focus (sedan, hatchback, etc.). You will almost certainly need to remove interior trim panels in the trunk area to access the latch mechanism. A repair manual specific to your year and model is highly recommended. You can often find these online (e.g., Haynes or Chilton manuals) or at auto parts stores.
Possible Solutions:
* Repairing the Cable/Rod: If it's disconnected, you might be able to reconnect it. If broken, replacement is necessary.
* Replacing the Latch Mechanism: This is often the most effective solution if the latch itself is faulty.
* Replacing the Actuator (power release): If it's the motor, replacement is necessary.
* Electrical Repairs: If wiring is the problem, you'll need to repair or replace the damaged wires.
Important Note: If you're not comfortable working on your car, it's best to take it to a qualified mechanic. Improperly working on your car's electrical system or latch mechanism could lead to further damage.
