Where is the flasher on a 1992 Buick Riviera located?

The flasher relay on a 1992 Buick Riviera is typically located under the dashboard, on the driver's side. However, it's *not* always in the same exact spot across all vehicles. It might be in a fuse box or a separate relay box. You'll likely need to consult a wiring diagram for your specific vehicle to pinpoint its exact location. A Haynes or Chilton repair manual for a 1992 Buick Riviera would be invaluable in this situation.
