1. Identify the Problem:
* Is the latch mechanism itself failing? Does the trunk seem to close partially but then pop back open? This suggests a problem with the latch assembly.
* Is the problem with the linkage? Are the rods and cables connecting the trunk release button, the key cylinder (if applicable), and the latch mechanism damaged, bent, or disconnected? This is a common cause.
* Is the trunk lid itself misaligned? Is the lid binding or rubbing against the body? This can prevent complete closure.
* Is there an obstruction? Check inside the trunk for anything preventing complete closure—spare tire, loose items, etc.
2. Troubleshooting Steps:
* Check for Obstructions: The first and easiest thing to do is thoroughly check the inside of the trunk for any obstructions that might be preventing complete closure.
* Inspect the Linkage: Open the trunk and carefully examine all the rods, cables, and linkages connected to the latch. Look for any bending, damage, or loose connections. Pay close attention to where these connect to the latch assembly. If anything is bent, you'll likely need to replace or straighten it. A disconnected cable is fairly easy to reconnect.
* Check the Latch Mechanism: With the trunk open, try to manually operate the latch mechanism. Does it engage and disengage smoothly? If it's stiff or doesn't work properly, the latch itself may be worn or damaged and require replacement.
* Examine the Trunk Lid Alignment: Closely inspect the trunk lid for any signs of misalignment. Look for binding or rubbing against the body. You might need to adjust the hinges or striker plate (the metal piece the latch engages with).
* Test the Release Mechanisms: Try releasing the trunk using both the interior release button and the key cylinder (if equipped). If one works and the other doesn't, it indicates a problem with that specific mechanism's linkage or the cylinder itself.
3. Repair/Replacement:
* Minor Linkage Adjustments/Repairs: If the linkage is slightly bent or disconnected, you might be able to straighten it or reconnect it. However, if it's significantly damaged, replacement is necessary.
* Latch Replacement: A faulty latch assembly usually requires replacement. This will involve purchasing a new latch mechanism (check a parts store or online retailer, providing your VIN for accuracy). Replacement can be tricky, requiring some mechanical aptitude; you may need to consult repair manuals or videos.
* Trunk Lid Alignment Adjustment: Adjusting the trunk lid hinges can be complex and may require careful measurement and adjustment. If you're not comfortable doing this, a body shop is recommended.
* Professional Help: If you're not comfortable with any of these repairs, it's best to take your car to a qualified mechanic or body shop. Attempting repairs without the proper knowledge could lead to further damage.
Finding Parts:
You can find parts (latch, linkages) for your 1996 Lincoln Town Car at various online retailers specializing in auto parts (like RockAuto, AutoZone, etc.) or at local auto parts stores. Always provide your vehicle's VIN for accurate part identification.
Remember safety first! Disconnect the battery negative terminal before working on any electrical components. If you're unsure about any step, consult a professional.
