Where are the flashers located on a 1987 Buick Century?

On a 1987 Buick Century, the turn signal flashers (hazard lights included) are typically located underneath the dashboard, usually near the center. They're often part of a larger assembly containing other relays. You'll likely need to access them by removing a panel or section of the dashboard. Precise location might vary slightly depending on trim level. A repair manual specific to your 1987 Buick Century would give the most accurate location.
