Where is the computer located on a 2000 Buick Century?

There isn't a single "computer" in a 2000 Buick Century in the way a desktop computer exists. Instead, it uses several Electronic Control Units (ECUs) or modules, often called "computers" colloquially. These are distributed throughout the vehicle. The most important ones include:

* Powertrain Control Module (PCM): This is arguably the "main" computer, controlling engine functions, transmission, and other powertrain components. It's typically located under the hood, often near the firewall. The exact location might vary slightly depending on engine type.

* Body Control Module (BCM): This controls many of the car's electrical systems, including lights, locks, windows, and some interior functions. This is usually located inside the passenger compartment, often under the dash, but its location can be tricky to access.

* Other Modules: There might be additional modules for things like anti-lock brakes (ABS), airbags, climate control, etc. These are scattered throughout the vehicle.

To locate a specific module, you'd need a wiring diagram or a service manual specific to your 2000 Buick Century. These diagrams show the location of each ECU. You can find these online through various automotive repair resources or at a parts store. Be aware that accessing some ECUs might require removing interior panels or other components.
