To find it precisely:
1. Consult your owner's manual: This is the best resource. It will show you a diagram of the fuse box and usually identifies the flasher relay.
2. Look for a fuse box diagram: There's usually a diagram on the inside cover of the fuse box itself. The diagram will identify each fuse and relay by function (e.g., "Turn Signals").
3. Check online resources: Search for "1995 Pontiac Grand Am fuse box diagram" on Google Images or similar search engines. You might find a diagram that shows the flasher relay's location.
The flasher relay itself is usually a small, square or rectangular component, possibly with a plastic clip for easy removal. Be sure to turn the ignition off before attempting to access or replace it.
