Tools and Materials

Before getting started, gather the following tools and materials:

  • Flathead screwdriver
  • Phillips screwdriver
  • Ratchet wrench
  • Socket set
  • Trim removal tool
  • Protective gloves

Step 1: Preparation

Ensure that your vehicle is parked in a safe and well-lit working area. Turn off the engine and disconnect the negative battery cable to prevent any electrical mishaps. Put on a pair of protective gloves to avoid any potential injuries during the removal process.

Step 2: Removing the Lower Dash Panel

Start by locating the screws or clips that secure the lower dash panel. Use a flathead screwdriver or a trim removal tool to carefully pry off the panel. Be gentle to avoid damaging any fragile components.

Step 3: Disconnecting Electrical Connections

Once the lower dash panel is removed, locate any electrical connections attached to the right under dash panel. Carefully disconnect each connection by gently pressing on the release tab or sliding it off.

Step 4: Removing the Mounting Screws

Next, locate the mounting screws that secure the right under dash panel. These screws are typically located at the top and bottom corners. Use a Phillips screwdriver or a ratchet wrench with the appropriate socket size to loosen and remove the screws.

Step 5: Panel Removal

After the screws are removed, you can now gently pull the right under dash panel away from the vehicle's frame. Take caution not to exert excessive force to prevent any potential damage.

Step 6: Inspection and Maintenance

With the right under dash panel removed, take this opportunity to inspect the area for any signs of wear, damage, or loose wiring. Perform any necessary maintenance or repairs before reinstalling the panel.

Step 7: Reinstallation

To reinstall the right under dash panel, follow the removal steps in reverse order. Ensure that all electrical connections are securely reattached and the mounting screws are tightened properly. Align the panel with the vehicle's frame and gently push it back into place until it snaps in securely.
