Tools You'll Need:
* New driver's side power mirror: Make sure you get the correct replacement for your year and model.
* Screwdrivers: Phillips head and possibly flathead, depending on your mirror's mounting.
* Socket wrench and sockets: You might need this depending on the type of fasteners.
* Panel removal tools (optional but helpful): These prevent scratching the interior trim.
* Wire connectors (optional): If your old connectors are damaged.
* Electrical tape (optional): For securing wires.
* Gloves: To protect your hands.
Steps:
1. Interior Door Panel Removal: This is the most challenging part. The exact procedure varies slightly depending on the trim level, but generally involves:
* Remove the door handle bezel: Usually held on by screws or clips.
* Remove the window crank bezel (if applicable): Again, screws or clips.
* Remove the door panel: There are typically several clips and screws securing the panel to the door. Gently pry the panel away from the door, using panel removal tools to avoid damage. Be careful of the wiring harnesses connected to the power window switch, door lock, and speakers. Disconnect these connectors. Some panels have a vapor barrier that might need to be detached carefully.
2. Locate the Mirror Connector: Once the door panel is removed, you'll see the wiring harness connected to the power mirror. Disconnect the electrical connector carefully.
3. Remove the Mirror: The mirror itself is usually attached to the door with screws or bolts. Locate and remove these fasteners. Depending on the model, you may need to access fasteners from inside the door after removing the door panel.
4. Install the New Mirror: Carefully align the new mirror with the mounting points on the door. Secure it with the screws or bolts.
5. Reconnect the Wiring Harness: Carefully plug the electrical connector back into the new mirror.
6. Reinstall the Door Panel: Reverse the steps from the removal process. Make sure all the connectors are securely plugged in and all the clips and screws are in place.
7. Test the Mirror: Connect the negative battery terminal. Test the new mirror's functionality using the mirror controls on your dashboard.
Important Notes:
* Consult a repair manual: A repair manual specific to your 1998 GMC Jimmy will provide detailed diagrams and instructions. This is highly recommended.
* Take Pictures: Before you start disassembling anything, take pictures of each step. This will help you remember how to reassemble the door panel correctly.
* Be Gentle: Use caution when removing clips and fasteners to avoid breaking them.
* If Unsure, Seek Professional Help: If you're uncomfortable with any of these steps, it's best to take your vehicle to a qualified mechanic.
Remember, this is a general guide. The exact procedure might vary slightly depending on your specific GMC Jimmy model and trim level. Always refer to a repair manual for precise instructions tailored to your vehicle.
