1. Preparation:
* Safety First: Park your vehicle on a level surface, engage the parking brake, and turn off the engine. If working outside, consider wearing safety glasses.
* Gather Tools: You'll likely need a small flathead screwdriver (possibly a trim removal tool for a cleaner job), possibly a Phillips head screwdriver, and potentially some plastic pry tools to avoid scratching the trim. You may also need a towel or rag to protect the door panel.
2. Removing the Mirror Housing:
* Locate the Access Panel: The process often starts with removing a small access panel on the inside of the door, usually near the mirror's mounting point. This might be held in place by clips or screws. Use the appropriate tools carefully to avoid breaking any clips.
* Disconnect Electrical Connections (If Applicable): If your mirror is power-adjustable and/or heated, there will be electrical connectors behind the access panel. Gently disconnect these connectors. Take a picture before disconnecting to help with reassembly.
* Remove the Mirror Housing: Once the access panel is removed, you should be able to access the screws or clips holding the mirror housing in place. Carefully remove these fasteners, freeing the mirror assembly. The method will vary: some might have visible screws, others might require releasing retaining clips carefully.
3. Removing the Mirror Glass (if necessary):
* Depending on the design: Sometimes, the glass is easily removed after the housing is off. There may be clips holding it on, or a small tab to release. If the glass is separate, be extra careful not to break it.
4. Installing the New Mirror:
* Reverse the Removal Process: Install the new mirror by following the steps you took to remove the old one in reverse order. Make sure all clips are securely fastened and that the electrical connections (if any) are properly reconnected.
5. Testing:
* Check Functionality: Test the power adjustments and heating function (if applicable) to ensure everything is working correctly.
Important Considerations:
* Type of Mirror: Is your mirror a standard manual mirror, power-adjustable, power-folding, or heated? The process will be slightly different for each.
* Parts Sourcing: Ensure you purchase the correct replacement mirror for your 1999 Oldsmobile Aurora. Provide your vehicle's VIN to ensure compatibility with parts vendors.
* Professional Help: If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Replacing the mirror incorrectly could cause further damage.
Remember, this is a general guide. The exact steps might differ depending on your Aurora's specific features. Always consult your owner's manual or a repair manual specific to your vehicle year and model for detailed instructions. Visual aids, such as YouTube videos showing a similar mirror replacement on a similar vehicle, can also be very helpful.
