* Trunk Release Switch: The button itself might be faulty. It could be stuck, internally shorted, or simply worn out. Try cleaning it with contact cleaner (electrical contact cleaner, not general purpose). If that doesn't work, replacement is the next step.
* Wiring Harness: The wiring between the trunk release button and the trunk latch mechanism could be damaged or corroded, especially near the hinges where the wires flex. Inspect the wiring carefully for breaks, chafing, or corrosion. Pay close attention to the area where the wiring enters the trunk.
* Trunk Latch Mechanism: The latch itself could be malfunctioning. It might be jammed, have a broken linkage, or have a faulty solenoid (the electrical part that actually unlocks the latch). This is usually the most expensive fix, potentially requiring replacement of the whole latch assembly.
* Body Control Module (BCM): The BCM controls many electrical functions in the car, including the trunk release. A faulty BCM is less likely, but possible. Diagnosing this requires specialized tools and expertise.
* Key Fob (if applicable): If your key fob has a trunk release button, try it. If that works, the problem is likely the interior button or its wiring.
Troubleshooting Steps:
1. Clean the Trunk Release Button: This is the easiest and cheapest fix to try first. Use electrical contact cleaner.
2. Check the Wiring: Carefully examine the wiring harness leading from the trunk release switch to the latch. Look for any visible damage. You may need to remove some interior trim panels to access the wiring completely.
3. Manually Unlock the Trunk: See if you can manually open the trunk using the key. If it opens with the key, the problem is electrical. If it doesn't, the problem is mechanical with the latch.
4. Test the Latch Solenoid (Advanced): If you have a multimeter, you can test the solenoid for continuity. This requires some electrical knowledge and accessing the solenoid. Look up a wiring diagram online for your specific year and model to locate the solenoid and its connections.
5. Consult a Repair Manual: A repair manual specific to your 2000 Dodge Intrepid will have detailed diagrams and troubleshooting steps.
6. Professional Mechanic: If you're uncomfortable working with car wiring or the latch mechanism, take your car to a qualified mechanic. They have the tools and expertise to diagnose the problem accurately.
Remember safety first! Always disconnect the negative battery terminal before working with car electrical systems.
