Where is the ignition module on 1996 Buick Century located?

The 1996 Buick Century's ignition module isn't a separate, easily identifiable box like in some older vehicles. Instead, the ignition control module is integrated into the Powertrain Control Module (PCM). The PCM is usually located under the instrument panel, on the driver's side. You'll likely need to remove some interior panels to access it. It's a fairly large, rectangular electronic control unit.
