1. Check the Obvious:
* Is the trunk truly locked? Sometimes, the key or remote isn't fully engaging, or the latch mechanism is just slightly misaligned. Try multiple times with the key or remote.
* Is something blocking the latch? Inspect inside the trunk and around the latch mechanism. Loose items, luggage, or even debris can prevent the latch from engaging properly.
* Is the trunk release cable disconnected or broken? The cable runs from the interior release lever to the trunk latch mechanism. Check under the back seat or in the trunk area (you may need to remove some interior panels) to see if the cable is detached or frayed. If broken, you'll need a replacement cable.
2. Troubleshooting the Latch Mechanism:
* Inspect the latch itself: With the trunk open, carefully examine the latch mechanism. Look for any obvious damage, broken parts, or signs of rust or corrosion. This might involve removing some interior panels for better access.
* Lubricate the latch: A well-lubricated latch mechanism can often solve problems caused by sticking or binding. Use a penetrating lubricant like WD-40 (temporarily) or a silicone-based spray lubricant for longer-term protection. Spray it into the latch mechanism and work the latch several times.
* Check the striker plate: This is the metal piece on the car body that the latch engages with. Make sure it's securely attached and isn't bent or damaged.
3. More Involved Repairs (Often Require Mechanical Skill):
* Replace the trunk latch assembly: If inspection reveals a damaged latch, the most reliable solution is often replacement. You'll need to obtain a new latch assembly for your 1997 Chevy Cavalier (ensure compatibility with your model). This involves removing the old latch and installing the new one, often requiring tools and some mechanical aptitude.
* Replace the trunk release cable: If the cable is broken, you'll need a replacement. This requires accessing and detaching the old cable and installing the new one, often requiring disassembly of interior panels.
* Electrical Issues (Remote Release): If the problem only occurs when using the remote or the interior release button, there could be an electrical fault in the wiring, the trunk release switch, or the central locking system. Diagnosing electrical issues requires more advanced troubleshooting techniques and may require a multimeter.
Where to Find Parts and Information:
* Auto Parts Stores: Local auto parts stores (like AutoZone, Advance Auto Parts, etc.) can help identify the correct latch assembly and cable for your car. They may also have diagrams or repair guides.
* Online Retailers: Websites like Amazon, eBay, or RockAuto sell replacement parts.
* Repair Manuals: A Haynes or Chilton repair manual for your 1997 Chevy Cavalier will provide detailed instructions and diagrams for accessing and repairing the trunk latch mechanism.
Important Considerations:
* Safety First: Always disconnect the battery negative terminal before working on electrical components.
* Tools: You'll likely need basic hand tools (screwdrivers, pliers, possibly sockets) for any repair work.
* Mechanical Ability: Some repairs are more challenging than others. If you're not comfortable working on your car, consider taking it to a qualified mechanic.
If you can provide more details about the specific problem (e.g., the trunk won't open at all, it opens only sometimes, the remote doesn't work, etc.), I might be able to offer more targeted advice. Remember to always consult a repair manual for your specific vehicle model for detailed instructions and diagrams.
