Tools You'll Likely Need:
* New side view mirror: Make sure you get the correct replacement for your Avalanche's year and specific features (heated, power-adjustable, turn signal, etc.).
* Phillips head screwdriver (possibly Torx): The type of screwdriver will depend on the mirror's mounting screws.
* Panel removal tools (optional): These plastic tools help prevent scratching the door panel when removing it (highly recommended).
* Socket wrench (possibly): In some cases, you might need a socket to remove nuts.
* Gloves: To protect your hands.
* Possibly a small flathead screwdriver or trim tool: For gently prying things loose.
Steps:
1. Disconnect the battery (recommended): This prevents accidental short circuits and keeps your power windows and locks from malfunctioning. This is an important safety precaution.
2. Remove the door panel: This is usually the most involved step. It involves:
* Locating and removing the door handle cover: Often held on by clips. Gently pry it off using your fingers or panel removal tools.
* Removing the window crank (if applicable): This usually involves unscrewing it.
* Removing other interior door components: Depending on your trim level, you might have other panels or covers to remove (e.g., armrest, speaker cover). Use panel removal tools to carefully pry off these components. They are typically held in place by clips.
* Detaching the door panel itself: Carefully unclip the door panel from the door. There will be several clips, and working slowly is key to avoid breaking them. Check carefully before prying to identify the clips. The panel usually slides out or pulls off after all the clips are released.
3. Access the mirror mounting: Once the door panel is removed, you'll see the mirror's mounting mechanism.
4. Disconnect the electrical connectors: Unplug the wiring harness connected to the mirror (heated, power-adjustable, turn signal).
5. Remove the mounting bolts or screws: Unscrew or remove the bolts or screws holding the mirror to the door. This will be different depending on the year and model.
6. Remove the old mirror: Carefully pull the old mirror away from the door.
7. Install the new mirror: Reverse the removal process to install the new mirror. Make sure the electrical connectors are securely plugged in.
8. Reassemble the door panel: Carefully reattach all the panels and components you removed earlier. Make sure all the clips are properly secured.
9. Reconnect the battery: Reconnect the negative (-) battery cable.
10. Test the mirror: Test all functions of the new mirror (power adjustment, heating, turn signal).
Important Considerations:
* Take pictures: Before you start, take pictures of every step to help you remember how everything goes back together.
* Work slowly and carefully: Rushing can easily damage the clips or other parts of the door panel.
* Be gentle: Use plastic panel removal tools to prevent scratching the door panel.
* If unsure, consult a professional: If you're not comfortable performing this repair yourself, it's best to take your Avalanche to a qualified mechanic.
