1. Check Your Owner's Manual: This is the first and best place to look. The owner's manual should have a detailed diagram of the fuse box(es) – many Cadillacs of that era had multiple fuse boxes.
2. Online Repair Manuals: Websites like Haynes.com and Chilton.com often sell digital or downloadable repair manuals for older vehicles. These manuals typically include detailed fuse box diagrams and explanations. They're a paid resource, but offer the most comprehensive information.
3. Online Forums and Communities: Search online forums dedicated to Cadillac Broughams or classic Cadillac enthusiasts (e.g., forums on sites like ClassicCars.com or dedicated Cadillac forums). Members might have scanned diagrams they can share, or offer guidance on finding one.
4. Use Google Images (with caution): Search for "1987 Cadillac Brougham fuse box diagram." While you might find some images, always verify the source and accuracy. A poorly scanned or incorrectly labelled diagram can be misleading and potentially harmful.
5. Local Auto Parts Stores: Some auto parts stores (like AutoZone, Advance Auto Parts, etc.) might have access to repair manuals or diagrams through their computer systems. It's worth asking, but they may not have the specifics for such an older model.
6. Cadillac Dealerships (Long Shot): While unlikely, you could contact a Cadillac dealership. They might have access to old service manuals or be able to guide you to a reliable resource.
Important Considerations:
* Multiple Fuse Boxes: The 1987 Brougham likely had more than one fuse box – one under the hood and potentially one inside the car (often under the dash). Be sure to look for diagrams for all locations.
* Diagram Accuracy: Always double-check the amperage ratings of fuses before replacing them. Using an incorrect fuse can cause damage to your vehicle's electrical system.
By using a combination of these methods, you should be able to find a reliable fuse box diagram for your 1987 Cadillac Brougham. Remember to prioritize official sources like owner's manuals and reputable online repair manuals for the most accurate information.
