1. Preparation:
* Disconnect the battery: This is crucial to prevent electrical shorts and accidental activation of the wipers.
* Gather tools: You'll likely need a small flathead screwdriver, possibly a small Phillips head screwdriver, and possibly a trim tool (plastic pry tool to avoid scratching).
2. Steering Column Cover Removal:
* Lower steering wheel: Some models allow you to lower the steering wheel column. Check your owner's manual or search for instructions specific to your Brougham. This will dramatically improve access.
* Remove the lower steering column cover: This is usually held on by clips. Carefully pry it off starting at one edge, working your way around. Use a trim tool to avoid damage. Be mindful of any wiring harnesses or connectors behind it.
3. Wiper Switch Removal:
* Locate the switch: The wiper switch is usually located on the steering column, often below the turn signal stalk.
* Disconnect the wiring harness: There's a connector plugged into the back of the switch. Carefully disconnect this connector. Take pictures or make notes of the connector's position to ensure correct reassembly.
* Remove the switch itself: The switch might be held in place by a retaining clip or screw. Look carefully for these. It might require some gentle wiggling or prying to release it. Use caution to avoid breaking any tabs or clips.
4. Reassembly:
* Reverse the steps above. Ensure the wiring harness is correctly connected.
Important Considerations:
* Consult a repair manual: A repair manual specific to your 1989 Cadillac Brougham will provide detailed diagrams and instructions. This is highly recommended.
* Take pictures: Before disconnecting anything, take pictures to aid in reassembly.
* Be gentle: Use caution when prying and removing parts to avoid damage.
* Patience is key: This process can be fiddly and require patience.
If you're not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improperly disconnecting or reconnecting the wiring harness could cause damage to your vehicle's electrical system.
