Tools You'll Need:
* Panel Removal Tool: A plastic trim removal tool set is highly recommended. These prevent scratching the panel and help pry out clips without breaking them. A flathead screwdriver can work in a pinch, but use extreme caution to avoid damage.
* Phillips Head Screwdriver: You'll likely need this to remove screws.
* Possibly a 10mm Socket and Ratchet: Some models have screws requiring this.
Steps:
1. Power Window & Lock Disconnection: If your Suburban has power windows and/or locks, disconnect them *before* removing the panel. This usually involves a small connector behind the panel you'll need to carefully unplug. Look for a connector with several wires coming from it near the window switch or lock mechanism.
2. Remove Door Handle: Often, the interior door handle will need to be detached. Look for screws behind the handle itself (usually a small cover needs to be popped off first) or under a small access panel. There may also be a retaining clip.
3. Remove Armrest/Storage Area (If Applicable): If there's a removable armrest or storage area in the door panel, remove it first. This usually involves unclipping or unscrewing it.
4. Remove Screws: Locate and remove any visible screws holding the door panel in place. These are typically located around the edges of the panel, near the armrest area, or sometimes near the bottom of the door.
5. Release the Clips: The door panel is held in place by a series of plastic clips. Carefully use your trim removal tool to pry the panel away from the door, starting at the bottom edge. Work your way around the perimeter, carefully releasing each clip as you go. The clips can be fragile, so gentle pressure is key. Expect some resistance as the clips release.
6. Disconnect the Door Panel: Once all the clips are released, carefully pull the door panel away from the door, being mindful of any remaining wiring connectors.
7. Disconnect Wiring Connectors: After the panel is loose, disconnect any remaining wiring harnesses. These might include the window switch, lock switch, courtesy light, and speaker wiring.
Important Considerations:
* Take Pictures: Before you start, take pictures of the panel and its position relative to the door. This will be invaluable when you reinstall it.
* Be Gentle: Avoid using excessive force, which could damage the clips or the door panel itself.
* Patience: This process can take some time and patience, especially if you're unfamiliar with it.
If you get stuck: Searching YouTube for "1990 Chevy Suburban door panel removal" will likely yield many helpful videos showing the process visually. Be sure to specify the trim level of your Suburban (e.g., "1990 Chevy Suburban door panel removal, base model") for better results.
Remember safety first! If you are uncomfortable performing this task, it's best to take your Suburban to a professional auto repair shop.
