1. Under the dashboard: This is a common location for many vehicles. You might need to remove some panels under the steering column to access it. Look for a small, square or rectangular box with wires attached.
2. In the fuse box: The Alero's fuse box is usually located under the hood. The flasher relay might be integrated into the fuse box itself, or it could be a separate relay within the box. Check your owner's manual's fuse box diagram. This diagram will show the location of each fuse and relay.
The most reliable way to find it is to consult your 2002 Oldsmobile Alero's owner's manual. The diagram in the manual will specifically show the location of the turn signal flasher relay. If you don't have the manual, you can usually find a digital version online through a site like Repair Manual.
Without the manual, searching online for "2002 Oldsmobile Alero fuse box diagram" might provide a diagram showing the relay's position, but it's not guaranteed to be accurate for every trim level.
