* Wiring Diagrams: These show the paths of electrical circuits throughout the car. You can usually find these diagrams in a repair manual specific to your 2001 Buick Century. These manuals are available from auto parts stores (like AutoZone, Advance Auto Parts, etc.) either physically or as digital downloads. You might also find some partial diagrams online through forums dedicated to Buick Century owners. However, be cautious about the accuracy and completeness of online sources.
* Component Diagrams: These show how parts are assembled within a subsystem (e.g., the engine, transmission, braking system). Again, a repair manual is your best bet for finding these.
* Body Diagrams: These show the assembly of body panels and parts. Repair manuals, and sometimes parts catalogs from GM (if you can find access), may contain these.
To find what you need, you should:
1. Identify your exact engine and transmission: The 2001 Buick Century came with various engine and transmission options. This information is crucial to get the correct diagrams. Your vehicle identification number (VIN) will help determine the exact specifications.
2. Obtain a repair manual: This is by far the most reliable and comprehensive source. Look for a factory service manual or a Haynes/Chilton manual (although these are often less detailed).
3. Search online forums: Websites and forums dedicated to Buick Century owners may have some diagrams or discussions that could be helpful, but always verify information from multiple sources.
In short, there's no single schematic; you need to be specific about what system you're working on and use the appropriate resources (primarily a repair manual) to find the relevant diagrams.
