Tools you will likely need:
* New replacement mirror: Ensure you get the correct one for your vehicle's year, model, and options (power, heated, etc.).
* Screwdrivers: Phillips head and possibly flathead.
* Wrench(es): May be needed depending on how the mirror is attached.
* Socket set: Possibly needed, especially if you have power adjustments.
* Electrical tape (if needed): For securing wiring.
* Panel removal tools (optional but helpful): These help avoid scratching the door panel.
* Interior door panel removal tool (possibly): You may need to remove the interior door panel to access the mirror's wiring and mounting.
General Steps:
1. Disconnect the battery: This is crucial to prevent short circuits.
2. Remove the interior door panel: This usually involves removing screws around the door handle, armrest, and possibly under the door pull. Carefully pry the panel away from the door using panel removal tools to avoid damage. There are usually plastic clips holding it in place; try to release these carefully. Once removed, carefully note how the panel was attached to aid in reinstallation.
3. Disconnect the electrical connector: Locate the electrical connector for the mirror (if power-adjustable and/or heated). Carefully disconnect it; take a picture to help with reconnection.
4. Remove the mirror: This is where things can get tricky and vary depending on your mirror type. Look for screws holding the mirror housing to the door. There may be screws on the inside or visible from the outside. You might need to remove some plastic covers to access them. Once the screws are removed, the mirror housing should come off.
5. Install the new mirror: Reverse the removal process, making sure to reconnect the electrical connector securely. If the mirror has a gasket, replace it to ensure a watertight seal.
6. Reattach the interior door panel: Carefully snap or screw the door panel back into place.
7. Reconnect the battery: Once everything is reassembled and you've tested the mirror (if applicable), reconnect the negative battery terminal.
8. Test the mirror: Check the functionality of the new mirror (power adjustments, heating, if equipped).
Important Considerations:
* Power Mirrors: If your mirror is power-adjustable, the wiring can be more complex. Be very careful when disconnecting and reconnecting the electrical connector. A wiring diagram can be very helpful.
* Heated Mirrors: Heated mirrors also involve additional wiring.
* Mirror Type: The exact process varies depending on whether you have a manual or power mirror.
* Difficult Access: Some screws might be hard to reach. A small ratchet and extension might be beneficial.
If you are not comfortable with this repair, it's best to take your vehicle to a qualified mechanic. Replacing a door mirror is not extremely difficult for someone mechanically inclined, but improper installation can lead to problems. A YouTube search for "1996 Pontiac Bonneville door mirror replacement" might show videos demonstrating the process for your specific vehicle, but always use caution and prioritize safety.
