1. Safety First:
* Park on a level surface: Engage the parking brake firmly.
* Disconnect the battery's negative terminal: This prevents accidental short circuits.
2. Access the Mirror:
* Locate the mirror adjustment switch: You'll need to know if it's power or manual.
* Power Mirrors: Put the mirror in the fully extended position (if applicable). This makes it easier to access the mounting points.
* Exterior Panel Removal (If Necessary): For some models, you may need to remove a small exterior trim panel near the mirror base to access the mounting bolts or clips. This usually involves gently prying with a plastic trim tool to avoid scratching the paint. Start at the edges and work your way around.
3. Removing the Mirror:
* Manual Mirrors: These are usually held in place with screws or clips directly on the door. Unscrew or carefully unclip the mirror.
* Power Mirrors: This is typically a more involved process. You'll likely find either:
* Several screws or bolts: located behind a trim panel or directly on the mirror housing itself. Remove these carefully.
* Clips: Again, these may be concealed by a trim panel. Gently pry the mirror housing away from the door using plastic trim tools to avoid damage. Work slowly and carefully to avoid breaking any clips. There might be wiring connectors attached.
4. Disconnecting the Wiring Harness (Power Mirrors):
* Carefully disconnect the electrical connectors for power, heating, and/or turn signals. Note how they are connected for reassembly. Some connectors may have clips that need to be squeezed or pushed to release. Take pictures if it helps.
5. Installing the New Mirror:
* Reversing the removal process: Carefully align the new mirror with the mounting points.
* Connect the wiring harness (if applicable): Ensure all connectors are securely plugged in.
* Secure the mirror: Tighten the screws or clips.
* Reconnecting the Trim Panel (if applicable): Carefully push the trim panel back into place, making sure it snaps securely.
6. Testing:
* Reconnect the battery: Test the new mirror to ensure all functions (adjustment, heating, folding if applicable) work correctly.
Important Considerations:
* Mirror Type: Ensure you purchase the correct replacement mirror for your specific vehicle. Note features like heating, power-adjusting, turn signal, and folding. The part number on your old mirror or your owner's manual will help.
* Tools: You'll likely need a screwdriver (likely Phillips head), possibly a socket set, and plastic trim removal tools.
* Patience: Take your time and be gentle to avoid breaking any clips or damaging the door panel. If you're unsure about any step, it's best to consult a professional.
