To find it:
1. Open the hood.
2. Locate the fuse block. It's usually a black rectangular box, often near the battery.
3. Consult your owner's manual. This is the most reliable way to identify the exact fuse for the turn signals. The manual will have a diagram showing the fuse box layout and what each fuse controls.
Without the owner's manual:
You'll likely find the turn signal fuse labeled as "TURN," "TURN SIGNAL," "FLASHER," or something similar. It's often a higher amperage fuse (e.g., 10A or 15A) than many others. If you can't find it labeled directly, try carefully testing fuses that *appear* to be a reasonable amperage and associated with lights. *Always turn the ignition off before checking fuses.*
Important Note: If you replace a blown fuse and it blows immediately again, there's a short circuit somewhere in your turn signal wiring. This requires professional diagnosis and repair to avoid further damage to your vehicle's electrical system.
