Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet and extensions
* Phillips and flathead screwdrivers
* Pliers
* Wire cutters/strippers (possibly)
* Electrical tape (possibly)
* New wiper motor
* Jack and jack stands (for safety)
* Shop rags or towels
Procedure (General Steps - Consult your repair manual for specifics!):
1. Disconnect the Battery: This is crucial to prevent electrical shorts and injury. Disconnect the negative (-) terminal first.
2. Access the Wiper Motor: This usually involves removing the cowl (the plastic cover under the windshield wipers). This might involve removing the wipers themselves, some screws or clips holding the cowl in place, and possibly some plastic fasteners. Your repair manual will show you exactly how the cowl is attached.
3. Disconnect Electrical Connectors: Carefully disconnect the electrical connector(s) from the wiper motor. Take pictures or make notes of how they are connected to help with reassembly.
4. Disconnect Linkage: The wiper motor is connected to the wiper arms through a linkage system. This will likely involve disconnecting several linkages and possibly removing some nuts and bolts securing the linkage to the motor and/or the car's body. Again, your repair manual will be invaluable here. Take pictures or notes.
5. Remove the Wiper Motor: Once the linkages and electrical connectors are disconnected, you'll need to remove the bolts or nuts holding the wiper motor in place. This may require some maneuvering and potentially removing other components to gain access.
6. Install the New Wiper Motor: Carefully install the new wiper motor, reversing the removal steps. Make sure the linkage is properly reconnected and all the bolts/nuts are tightened securely.
7. Reconnect Electrical Connectors: Reconnect the electrical connectors to the new wiper motor, ensuring they are securely attached.
8. Reconnect Linkage: Carefully reconnect the wiper linkage, ensuring it's properly aligned.
9. Reinstall the Cowl: Reinstall the cowl, making sure all screws and clips are properly secured.
10. Reconnect the Battery: Reconnect the battery's negative (-) terminal.
11. Test the Wipers: Turn on your wipers to ensure they are functioning correctly. If not, double-check all connections.
Important Considerations:
* Repair Manual: A repair manual specific to your 1997 Crown Victoria is absolutely essential. Generic instructions are not a substitute for detailed, vehicle-specific guidance.
* Safety: Use jack stands when working under the car. Never work under a vehicle supported only by a jack.
* Photography: Take lots of pictures during disassembly. This will be incredibly helpful during reassembly.
* Patience: This is not a quick job. Take your time and be methodical.
* Parts: Ensure you purchase the correct wiper motor for your specific vehicle.
If you're not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. This repair involves working with electrical components and potentially fragile parts, and incorrect installation could lead to further damage.
