To find it, you'll likely need to:
1. Consult your owner's manual: This is the best place to start. The manual should have a diagram showing the location of the flasher relay and other components under the dash.
2. Look for fuse boxes: Many flasher relays are located within fuse blocks. These are usually accessible by removing a panel under the dashboard.
3. Examine relay boxes: Some cars have separate relay boxes, often near the fuse block. Check for a relay of appropriate size that might be labeled "turn signal" or have a similar indicator.
4. Use an online forum or parts website: Search for "1993 Buick Century flasher relay location" on a car forum or parts website; someone else may have already documented its location.
Important Note: Before working on any electrical components, disconnect the negative terminal of your battery to prevent accidental short circuits.
