Here's a general procedure. Important Note: These instructions are a guide. There might be slight variations depending on your specific trim level. It's always best to consult a repair manual specific to your 1996 Lumina for precise details and diagrams.
1. Window Control: Roll the window all the way down. This will give you easier access and prevent damage to the window regulator.
2. Door Handle: You'll likely find screws hidden behind the door handle. Carefully pry off the handle bezel (the plastic piece around the handle) using a trim removal tool or a flathead screwdriver (wrapped in cloth to avoid scratching). There should be screws securing the handle mechanism; remove them. The handle assembly may or may not detach completely at this point; depending on how it is constructed.
3. Armrest: The armrest usually has screws hidden underneath. Remove the screws, and the armrest should come off.
4. Window Switch Panel: The power window switch panel may have screws holding it in or simply be held in place with clips. Carefully remove it. You'll need to disconnect the electrical connector for the switches before completely removing the panel.
5. Door Panel Clips: The door panel itself is held in place by numerous plastic clips. Starting at the bottom, carefully use a trim removal tool or a flathead screwdriver (again, wrapped in cloth) to pry the panel away from the door. Work your way around the perimeter, releasing the clips as you go. Be gentle to avoid breaking the clips; some are brittle and prone to damage.
6. Electrical Connectors: Once the panel is mostly loose, disconnect the electrical connectors for the door lock, power window switches (if applicable), and any other wiring harness. These connectors usually have a release lever or tab you need to depress to disconnect.
7. Removing the Panel Completely: Once all the clips are released and connectors are disconnected, the door panel should come off relatively easily.
8. Reassembly: Reassembly is simply the reverse of the removal process. Make sure to align the clips and secure everything before reconnecting the electrical connectors.
Important Considerations:
* Trim Removal Tools: Investing in a set of plastic trim removal tools is highly recommended to prevent scratches and damage to your door panel and interior.
* Patience: Take your time and be careful. Rushing can lead to broken clips or other damage.
* Repair Manual: As mentioned before, a repair manual specific to your 1996 Chevrolet Lumina will be invaluable for accurate instructions and diagrams.
This process is generally similar for most cars, but the exact locations of fasteners and clips can vary significantly. Again, using a repair manual specific to your vehicle is strongly advised.
