1. Preparation:
* Gather tools: You'll likely need a small screwdriver (possibly a Phillips head and a flathead), possibly some pliers, and potentially a trim removal tool to avoid scratching the interior. A flashlight will also be helpful.
* Locate the access panel: This is the crucial first step. The access panel is usually located within the trunk's inner panel, somewhere near the area where the fuel filler neck enters the car. It might be a small circular or rectangular panel, sometimes covered by a piece of fabric or carpeting. You may need to feel around to find it. Some models might have a readily visible panel, while others might require some careful investigation.
2. Accessing the Spring:
* Remove the access panel: Carefully remove the access panel. It might be held in place by clips or screws. Gently pry it open using your trim tool or screwdriver, being mindful not to break any clips.
* Inspect the mechanism: Once the panel is removed, you should see the fuel door spring mechanism. It usually consists of a spring connected to a small lever or arm that's attached to the fuel door. Take note of how it's connected before disconnecting anything. Take photos if it helps.
* Disconnect the old spring: Carefully disconnect the old spring from the lever. This might involve unhooking a small clip, removing a retaining pin, or simply carefully unhooking the spring from its attachment points.
3. Installation of the New Spring:
* Connect the new spring: Attach the new spring to the lever arm in the same manner as the old spring. Make sure it's properly seated and secure. Double-check your work against the photo or your memory of how it was originally attached.
* Test the fuel door: Test the fuel door to ensure the spring is working correctly and the fuel door opens and closes smoothly.
4. Reassembly:
* Replace the access panel: Carefully replace the access panel, ensuring all the clips are properly engaged or screws are tightened.
Important Considerations:
* Patience: This is a somewhat fiddly job. Take your time to avoid damaging anything.
* Reference material: If possible, try to find a repair manual or online forum specific to your 1991 Pontiac Grand Am. Pictures or videos would be extremely helpful.
* Parts: Ensure you have the correct replacement spring. A local auto parts store can help identify the correct part for your vehicle.
If you're uncomfortable working on your car yourself, it's always best to take it to a qualified mechanic. This avoids the risk of further damage to your vehicle.
