why does my Honda Civic 11th Generation (2022-Present) exterior lights keep blowing fuses?

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, and wire strippers.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect the Fuse Box

• Remove the cover of the fuse box.
• Visually check for burnt fuses; replace any that are blown.
• Clean any corrosion on terminals using electrical contact cleaner.

3. Examine the Wiring Harness

• Follow the wiring from the fuse box to the exterior lights.
• Look for frayed wires or any signs of wear; repair or replace damaged sections using appropriate gauge wire.
• Ensure all connectors are securely fastened and free from corrosion.

4. Test Light Sockets

• Use a multimeter to measure the voltage at the light socket.
• If voltage is outside the normal range, trace back to the fuse box and inspect for shorts or faulty connections.

5. Check Light Bulb Ratings

• Remove the light bulbs from their sockets.
• Verify the wattage of each bulb; replace any that are rated higher than specified in the owner's manual.
• Install new bulbs as needed, ensuring they are seated correctly in the sockets.

6. Reassemble and Test

• Reinstall the fuse box cover.
• Reconnect the negative battery terminal.
• Test the exterior lights to ensure they function correctly without blowing fuses.
