1. Open the Hood: Pull the release lever inside your car to release the hood.
2. Locate the Fuse Box Cover: Look for the fuse box cover under the hood, usually labeled "FUSE BOX" or similar.
3. Remove the Fuse Box Cover: Press the release tab or turn the knob (if any) to remove the fuse box cover.
4. Identify the Relay Fuse: Consult the fuse box diagram provided in your car's owner's manual to identify the specific location of the relay fuse for your model. The diagram will show the position and amperage of each fuse and relay.
5. Inspect the Relay Fuse: Remove the relay fuse from its socket using a fuse puller or tweezers. Inspect the fuse for any visible signs of damage, such as a broken filament.
6. Replace if Necessary: If the relay fuse is blown, replace it with a new fuse of the same amperage rating. Make sure to use a genuine Toyota fuse or one of equivalent quality.
7. Reinstall the Fuse Box Cover: Once you have replaced any blown fuses, put the fuse box cover back in place and secure it by pressing down or turning the knob, if applicable.
8. Close the Hood: Lower the hood and make sure it's securely closed before driving.
It's important to consult the specific fuse box diagram for your 2000 Toyota Celica to ensure that you accurately locate and inspect the relay fuse. The position of fuses and relays may vary depending on the vehicle's model and trim level.
