Before You Begin:
* Safety First: Disconnect the negative battery terminal to prevent electrical shorts.
* Gather Tools: You'll need a socket set (various sizes), screwdrivers (Phillips and flathead), pliers, a wrench, possibly a ratchet and extensions, and a new wiper motor. A shop rag or towels are also helpful.
* Repair Manual: A Chilton's or Haynes repair manual for your specific year and model Bravada will be invaluable. It provides detailed instructions, torque specifications, and diagrams.
General Steps (These are approximate and may vary):
1. Access the Wiper Motor: This typically involves removing the cowl (the plastic panel under the windshield). This often requires removing the wiper arms (after disconnecting the battery!), and possibly some screws and clips holding the cowl in place. Consult your repair manual for the exact procedure.
2. Disconnect Electrical Connections: Once the cowl is removed, you should see the wiper motor. Carefully disconnect the electrical connectors from the motor. Take photos or make notes to remember how everything connects for reassembly.
3. Remove the Wiper Motor Linkage: The wiper motor is usually connected to a linkage system that moves the wiper arms. Disconnect this linkage carefully. Again, refer to your repair manual for specifics, as the linkage design may vary slightly.
4. Remove Mounting Bolts: The wiper motor is secured to the firewall or body with several bolts. Carefully remove these bolts.
5. Remove the Wiper Motor: Once the bolts are removed, the wiper motor should be free to remove. It might be slightly snug, so gently wiggle it free.
6. Install the New Wiper Motor: Install the new wiper motor in the reverse order of removal. Make sure the linkage is properly connected and that the motor is securely bolted in place.
7. Reconnect Electrical Connections: Reconnect the electrical connectors to the new wiper motor, ensuring they are securely fastened.
8. Reinstall the Linkage: Reattach the wiper linkage.
9. Reinstall the Cowl: Reinstall the cowl, ensuring all screws and clips are properly secured.
10. Reconnect Wiper Arms: Reattach the wiper arms.
11. Reconnect Battery: Reconnect the negative battery terminal.
12. Test the Wiper Motor: Turn on your wipers and test all speeds to ensure the new motor is working correctly.
Important Considerations:
* Rust and Corrosion: Parts in the engine bay, especially older vehicles, can be prone to rust and corrosion. Penetrating oil may be helpful in loosening stubborn bolts.
* Torque Specifications: Always tighten bolts to the manufacturer's specified torque. Over-tightening can damage threads or components.
* Professional Help: If you're uncomfortable with any of these steps, it's best to take your vehicle to a qualified mechanic. Improper installation can lead to further damage or injury.
Remember, this is a general overview. Always consult your repair manual for specific instructions related to your 1997 Oldsmobile Bravada. The manual will provide detailed illustrations and torque specifications, ensuring a successful repair.
