The hazard light flasher on a 1997 Chevy Blazer S10 is typically located
under the dashboard, near the steering column. However, the exact location can vary slightly depending on trim level and specific options. It's often behind a small access panel or tucked away in a somewhat difficult-to-reach spot. You might need to remove a small panel or trim piece to access it.
Your best bet is to consult a repair manual specific to your 1997 Chevy Blazer S10. A Haynes or Chilton manual will provide diagrams and instructions showing its precise location. You can also search online for a wiring diagram of your vehicle, which may show the flasher's position within the overall electrical system.
