Tools You'll Likely Need:
* Socket wrench set (metric)
* Screwdrivers (Phillips and possibly flathead)
* Pliers (needle-nose might be helpful)
* Ratchet and extensions
* Possibly a trim removal tool (to avoid scratching plastic)
* New wiper motor (ensure you get the correct one for your Lumina model)
* Shop towels or rags
Steps:
1. Disconnect the Battery: This is crucial to prevent electrical shocks and short circuits. Disconnect the negative (-) terminal first.
2. Access the Wiper Motor: This is usually under the cowl (the plastic panel under the windshield). You'll likely need to remove the plastic cowl cover. This usually involves removing several clips and screws. Be gentle to avoid breaking the clips. Your repair manual will show the exact location and fasteners.
3. Disconnect the Wiper Motor Connections: Once you have access to the motor, disconnect the electrical connector. There might also be a linkage connected to the motor arm; disconnect this carefully. Take photos before disconnecting anything to help you remember how it goes back together.
4. Remove the Wiper Motor Mounting Bolts: The motor is typically held in place by several bolts. Use the appropriate sockets to carefully remove these bolts.
5. Remove the Wiper Motor: After removing the bolts, gently pull the motor out of its housing. There might be some resistance.
6. Install the New Wiper Motor: Carefully align the new wiper motor with its mounting points. Secure it with the bolts you removed earlier.
7. Reconnect Everything: Reconnect the electrical connector and the linkage to the wiper arm, ensuring everything is securely fastened. Double-check your work against your photos.
8. Reinstall the Cowl Cover: Carefully replace the cowl cover and secure it with the clips and screws.
9. Reconnect the Battery: Reconnect the negative (-) battery terminal.
10. Test the Wiper Motor: Turn on your wipers to ensure they are functioning correctly. Check for proper speed and operation in all positions.
Important Considerations:
* Repair Manual: A repair manual specific to your 1998 Chevrolet Lumina is invaluable. It will provide precise diagrams and instructions, minimizing the risk of damage.
* Safety: Always disconnect the battery before working on any electrical components.
* Patience: Take your time and be methodical. Rushing can lead to mistakes and damage.
* Professional Help: If you're uncomfortable working on your car's electrical system, consider taking it to a qualified mechanic.
This guide provides a general overview. Specific details will vary based on your Lumina's trim level and other factors. Always refer to your vehicle's repair manual for the most accurate and detailed instructions.
