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 small flathead screwdriver (possibly a trim removal tool), and possibly a Phillips head screwdriver depending on the mirror's mounting. Some people find a plastic trim tool helps avoid scratching the car.
* Observe the Mirror: Before you start, carefully examine how the mirror is attached. Take note of any clips, screws, or bolts. Take photos if it helps.
2. Removing the Mirror:
* Power/Heated Mirrors (Most Likely): These are generally more complex. There will likely be a small cover or access panel on the outside of the door near the mirror's base. Carefully pry this open with your flathead or trim tool. Inside you'll find either a screw or clip holding the mirror assembly to the door. Remove this fastener and carefully detach the mirror housing from the door. Disconnect the electrical connector for the power and heating elements. Be gentle as these connectors can be fragile.
* Manually Adjusted Mirrors (Less Common): These are usually simpler. They might just clip onto the door. Carefully pry the mirror assembly away from the door, working your way around the perimeter. There may be small clips holding it in place. If you encounter resistance, carefully inspect for screws or bolts before applying more force.
3. Installing the New Mirror:
* Reverse the Removal Process: Carefully connect the electrical connector (if applicable). Then, align the new mirror assembly with the mounting points on the door and securely attach it using the clips or screws you removed earlier.
* Test Functionality: If your replacement mirror is powered, test the adjustment and heating features to ensure they are working correctly.
Important Considerations:
* Mirror Type: Ensure you order the correct replacement mirror for your specific Grand Am model. Check your VIN number to be absolutely sure you get the right fit and features (power, heated, type of adjustment).
* Glass vs. Entire Assembly: You can often replace just the glass of a power mirror if the housing is still intact. This is generally cheaper and easier. However, if the housing is damaged, you'll need a complete assembly.
* Wiring: If you're dealing with electrical connectors, be very careful to avoid damaging them. If you're unsure about the wiring, consult a professional.
* Clips: The plastic clips that hold the mirror assembly are prone to breaking. If they do, you may need to source replacements.
If you are not comfortable performing this repair yourself, it's best to take your car to a qualified mechanic or auto body shop. They have the tools and expertise to do the job safely and efficiently. They can also source the correct replacement parts.
