Tools you'll likely need:
* Socket set (metric)
* Ratchet and extensions
* Screwdrivers (Phillips and flathead)
* Pliers
* Wire cutters/strippers
* Electrical tape
* New wiper motor
* Shop rags or towels
* Possibly a torque wrench
Steps:
1. Disconnect the Battery: This is crucial to prevent accidental short circuits. Disconnect the negative (-) terminal first.
2. Access the Wiper Motor: This is usually located under the cowl (the panel beneath the windshield). You'll likely need to remove the wiper arms and the cowl panel itself. This often involves removing nuts and bolts securing the wiper arms and then carefully prying off the cowl panel. Be careful not to damage the cowl panel during removal. Some plastic fasteners might break, so be gentle.
3. Disconnect Electrical Connections: Locate the electrical connector(s) going to the wiper motor. Carefully disconnect them, noting how they're connected for reassembly. Take photos if needed.
4. Disconnect Linkage: The wiper motor is connected to the wiper linkage. Disconnect this linkage. This may involve removing a nut, bolt, or clip. Again, take photos to help with reassembly.
5. Remove the Wiper Motor: Once the electrical connections and linkage are disconnected, remove the bolts or nuts holding the wiper motor in place. This might be tricky due to limited space.
6. Install the New Wiper Motor: Carefully install the new wiper motor, ensuring it's properly seated and aligned. Secure it with the bolts or nuts.
7. Reconnect Linkage: Reconnect the wiper linkage, making sure it's properly engaged.
8. Reconnect Electrical Connections: Reconnect the electrical connectors to the new wiper motor, matching them to how they were previously connected.
9. Reinstall Cowl Panel: Carefully reinstall the cowl panel, securing it with the fasteners.
10. Reconnect Wiper Arms: Reattach the wiper arms.
11. Reconnect Battery: Reconnect the battery's negative (-) terminal.
12. Test the Wiper Motor: Turn on your wipers to test the new motor. Check for proper operation on all speeds.
Important Considerations:
* Repair Manual: A repair manual specific to your 1992 Jeep Wrangler YJ is highly recommended. It will provide detailed diagrams and instructions specific to your model.
* Rust: Expect rust in this area, especially if your Jeep is older. Penetrating oil may help loosen rusted bolts.
* Patience: This is not a quick job. Take your time and be methodical.
* Safety: Always prioritize safety. Wear safety glasses and work in a well-ventilated area.
If you're uncomfortable performing this repair yourself, it's best to take your Jeep to a qualified mechanic. Replacing a wiper motor is a relatively inexpensive repair, and the cost of a professional repair will likely be less than the cost of damaging components during a DIY attempt.
