Tools you will likely need:
* Flathead screwdriver (preferably plastic or wrapped in tape to avoid scratching)
* Phillips head screwdriver
* Panel removal tools (plastic pry tools are best; these prevent scratching)
* Possibly a 10mm socket (depending on screw locations)
Procedure:
1. Disconnect the Power: Disconnect the negative terminal from your car battery. This is a safety precaution to prevent accidental short circuits.
2. Remove Door Handle Components (If Applicable): Some models have screws hidden behind the door handle assembly. You may need to carefully pry off the handle bezel (often with small clips) to access these screws. Be gentle; these are fragile.
3. Remove Window Crank (If Applicable): If you have a manual window crank, remove it. This usually involves pulling or twisting it to release it from its shaft.
4. Remove Door Panel Screws: Look for screws around the perimeter of the door panel. These are typically located at the bottom of the door, and possibly near the armrest or speaker. Remove all visible screws.
5. Release the Panel Clips: Once the screws are out, the door panel is held in place by plastic clips. Starting at the bottom edge, carefully insert your flathead screwdriver or panel removal tool into the gap between the door panel and the door frame. Gently pry the panel outward, releasing the clips one at a time. Work your way around the perimeter of the panel, releasing all the clips. Be extremely careful; these clips can break easily.
6. Disconnect Electrical Connectors: Once most of the panel is loose, carefully disconnect the electrical connectors for the door lock, power window (if applicable), and courtesy light. These connectors usually have a retaining tab or clip; gently press the tab while pulling the connector.
7. Remove the Door Panel: With all the clips released and connectors disconnected, gently pull the door panel away from the door frame. Be mindful of any remaining wiring or cables.
8. Repair the Window Mechanism: Now you have access to the window regulator and other components. Repair or replace the broken parts as needed.
9. Reassembly: Reassembly is the reverse of the removal process. Make sure all clips are properly seated and all connectors are firmly connected.
Important Notes:
* Take Pictures: Before you start, take pictures of how everything is connected – especially the electrical connectors. This will be invaluable when reassembling.
* Patience is Key: This process requires patience and a gentle touch. Rushing can easily lead to broken clips or other damage.
* Repair Manual: A repair manual specific to your 1992 Nissan Pathfinder will be incredibly helpful and will provide detailed diagrams and instructions. This is highly recommended.
If you're not comfortable performing this repair yourself, it's always best to consult a professional mechanic. Attempting this repair without the necessary knowledge or tools could lead to further damage.
