Here's a general outline of the process:
1. Preparation:
* Safety First: Park on a level surface, engage the parking brake, and turn off the engine. Wear safety glasses.
* Gather Tools: You'll likely need a trim removal tool (plastic pry tool is best to avoid scratching), possibly a screwdriver (depending on the mirror's fastening mechanism), and potentially a socket wrench if the mirror is bolted on. New replacement mirror.
2. Removing the Mirror:
* Locate the Access Points: Carefully examine the mirror housing. There are usually small clips or screws hidden beneath decorative covers or trim pieces around the mirror.
* Remove the Trim: Gently use the trim removal tool to pry off the plastic cover or trim pieces surrounding the mirror's base. Work slowly and carefully to avoid breaking the clips. Start at one corner and work your way around.
* Disconnect the Electrical Connector: Once the trim is removed, you'll see the electrical connector for the heated mirror (if equipped), turn signals, and possibly puddle lights. Carefully disconnect the connector by gently pressing on the release tab.
* Detach the Mirror: The mirror itself might be held on by screws or clips. Remove these fasteners to release the mirror.
3. Installing the New Mirror:
* Attach the Mirror: Carefully align the new mirror and reattach the screws or clips.
* Reconnect the Electrical Connector: Securely connect the electrical connector.
* Reattach the Trim: Carefully snap the trim pieces back into place, ensuring they are properly seated.
4. Verification:
* Test the Functionality: Test the mirror's adjustments, heating function (if applicable), and turn signals to ensure everything is working correctly.
Important Considerations:
* Types of Mirrors: Altimas may have different mirror types: manually adjusted, power-adjusted, power-folding, heated, etc. The replacement mirror must match your existing mirror's features.
* Getting the Right Replacement: Ensure you order the correct replacement mirror for your specific Altima year and model. The part number is crucial. You can find this information in your owner's manual or online through parts websites using your VIN.
* Difficult Removal: If you encounter significant resistance during removal, stop and consult your owner's manual or a professional mechanic. Forcing it can cause damage.
* Professional Help: If you're uncomfortable with any part of this process, it's best to take your Altima to a qualified mechanic or auto body shop. They have the right tools and expertise to avoid damage.
This is a general guide. The exact steps may vary depending on your specific Altima model year. Always prioritize safety and consult your owner's manual for detailed instructions.
