4. Removing the Door Panel

Removing the door panel is a crucial step in the 1999 Mercedes Benz E320 right rear window regulator replacement process. Follow these detailed instructions to remove the door panel without causing damage:

Step 1: Gather Your Tools

You will need a panel removal tool, a screwdriver set (both Phillips and flathead), and a Torx driver set. These tools will help you remove the various fasteners and clips that hold the door panel in place.

Step 2: Locate and Remove Screws

Inspect the door panel for any visible screws. Common locations include:

• Door Handle Recess: Check behind the door handle.
• Armrest: Look under the armrest, often covered by a small plastic cap.
• Bottom Edge of the Panel: Screws may be located along the bottom edge of the door panel.

Remove all identified screws using the appropriate screwdriver or Torx driver.

Step 3: Remove the Door Handle Trim

Carefully pry off the trim piece around the door handle. Use a plastic panel removal tool to avoid scratching the surrounding surface. Gently work around the edges until the trim piece comes loose.

Step 4: Disconnect Electrical Connections

Before fully removing the door panel, disconnect any electrical connections. This typically includes the power window switch and the door lock switch. Gently squeeze the connectors and pull them apart.

Step 5: Pry Off the Door Panel

Using the panel removal tool, start prying the door panel away from the door frame. Begin at the bottom corner and work your way around the edges. The panel is held in place by plastic clips, so apply gentle but firm pressure to release them.

Step 6: Lift and Remove the Door Panel

Once all the clips are released, lift the door panel upward to disengage it from the top edge of the door frame. Carefully pull the panel away from the door.

Step 7: Inspect the Door Panel

After removing the door panel, inspect it for any broken clips or damaged components. Replace any damaged parts to ensure a secure fit when reinstalling the panel.

By following these steps, you can safely and effectively remove the door panel to access the window regulator. Proper door panel removal is essential for completing the 1999 Mercedes Benz E320 right rear window regulator replacement.

5. Disconnecting Electrical Components

Disconnecting electrical components is a critical safety measure during the 1999 Mercedes Benz E320 right rear window regulator replacement. This step prevents electrical shorts and ensures your safety while working on the vehicle. Here’s how to properly disconnect the electrical components:

Step 1: Identify Electrical Connectors

Step 2: Disconnect the Window Motor

Locate the connector for the window motor. It is typically a multi-pin connector. Gently squeeze the locking tab on the connector and pull it straight out to disconnect it.

Step 3: Disconnect the Door Lock Actuator

Find the connector for the door lock actuator. Like the window motor connector, squeeze the locking tab and pull the connector straight out.

Step 4: Disconnect the Speaker Wires

If there are speakers in the door, disconnect the speaker wires. These may be simple push-on connectors or more complex multi-pin connectors. Disconnect them carefully.

Step 5: Disconnect the Power Window Switch

The power window switch on the door panel will have a connector attached to it. Disconnect this connector by squeezing the locking tab and pulling it out.

Step 6: Label Connectors (Optional)

To avoid confusion during reassembly, you can label each connector with a piece of tape indicating its corresponding component. This can save time and prevent mistakes when reconnecting the components.

Step 7: Secure the Wires

Once all the connectors are disconnected, secure the wires to the door frame using tape or zip ties. This will keep them out of the way while you work on the window regulator.

Safety Tips:

• Disconnect the Battery: Always disconnect the battery before working on electrical components to prevent shorts.
• Gentle Handling: Handle connectors gently to avoid damaging the pins or locking tabs.
• Inspect Connectors: Before reconnecting, inspect the connectors for any signs of damage or corrosion. Clean or replace them as needed.

Step 1: Gather Your Tools

You will need a drill, a set of drill bits (including a size slightly larger than the rivet diameter), safety glasses, and work gloves.

Step 2: Prepare the Work Area

Ensure the area around the rivets is clean and free of obstructions. Wear safety glasses to protect your eyes from flying debris and gloves to protect your hands.

Step 3: Select the Correct Drill Bit

Choose a drill bit that is slightly larger than the diameter of the rivet. This will allow you to drill out the rivet without damaging the surrounding metal. Start with a smaller bit if you are unsure, and gradually increase the size until the rivet head comes off easily.

Step 4: Position the Drill

Place the tip of the drill bit directly in the center of the rivet head. Apply firm, steady pressure to keep the drill from slipping.

Step 5: Drill Out the Rivet Head

Begin drilling at a slow speed, gradually increasing the speed as you gain control. Apply consistent pressure and keep the drill perpendicular to the rivet. Drill until the head of the rivet separates from the body.

Step 6: Remove the Rivet Body

Once the rivet head is removed, use a punch or a small screwdriver to push the remaining rivet body out of the hole. If the rivet is stubborn, you may need to use a smaller drill bit to carefully drill out the remaining portion.

Step 7: Repeat for All Rivets

Repeat the process for all rivets holding the window regulator in place. Take your time and be careful not to damage the surrounding metal.

Safety Tips:

• Wear Safety Glasses: Always wear safety glasses to protect your eyes from flying metal debris.
• Use the Right Drill Bit: Using the correct size drill bit is crucial to avoid damaging the surrounding metal.
• Apply Steady Pressure: Apply consistent pressure to the drill to prevent it from slipping.
• Take Your Time: Rushing the process can lead to mistakes and potential damage.
