Tools You'll Likely Need:
* New side view mirror: Ensure you get the correct replacement for your Bonneville (power or manual). Check the part number on the old mirror or get it from a parts store using your VIN.
* Phillips head screwdriver: Possibly a small flathead screwdriver.
* Plastic trim removal tools (optional but recommended): These help prevent scratching the plastic trim. If you don't have these, you can use something like a dull butter knife or a credit card.
* Towel or rag: To protect the paint.
Steps:
1. Preparation: Park your Bonneville on a level surface, engage the parking brake, and turn off the engine. It might be helpful to disconnect the negative terminal of the car battery if you're working with a power mirror to avoid accidental short circuits.
2. Remove the Door Panel (Partially or Fully): This is the most crucial and potentially tricky step. You'll need to access the back of the mirror housing. This usually involves:
* Locating the access points: Look for screws hidden beneath the door handle, armrest, or other trim pieces. There are often small plastic covers you need to carefully pry off with your trim tools.
* Removing the screws: Once you find the screws, carefully remove them.
* Gently releasing the panel: The door panel is typically held in place by clips. Work your way around the perimeter of the panel using your trim tools or a flat object to gently pry it away from the door. Be patient and work slowly to avoid breaking the clips. *You may not need to fully remove the panel; sometimes, enough of it can be loosened to access the mirror.*
3. Disconnect the Mirror: Once you have access to the back of the mirror assembly:
* Power Mirrors: You'll likely need to disconnect the electrical connector. It usually just pulls apart.
* Manual Mirrors: There's no electrical connection.
4. Remove the Mirror Housing: This usually involves removing some screws or clips holding the mirror housing to the door. Again, take your time and be gentle.
5. Install the New Mirror: Reverse the removal process to install the new mirror. Make sure the electrical connector is securely attached (if applicable).
6. Reassemble the Door Panel: Carefully snap the door panel back into place and secure it with the screws.
7. Test the Mirror: Test the functionality of the new mirror (adjustment, heating, if applicable).
Important Considerations:
* Power Mirrors: If your mirror is heated or power-adjustable, be extra careful when disconnecting and reconnecting the electrical connectors. Refer to a wiring diagram if you're unsure.
* Clips: Door panel clips are often fragile. If you break any, you might need to replace them.
* Manual vs. Power: The procedure will be slightly different depending on whether you have manual or power mirrors. The power mirror will have the additional wiring.
* YouTube Videos: Search YouTube for "1998 Pontiac Bonneville side mirror replacement" for visual guidance. This will often show specific details for your model year.
If you're not comfortable doing this yourself, it's best to take your car to a qualified mechanic or auto body shop. Replacing the mirror incorrectly could damage your door panel or other components.
