Solution

1. Preparation

Gather tools: multimeter, socket set, screwdrivers, wire strippers, and electrical tape.
Disconnect the vehicle battery to ensure safety while working on the electrical system.

2. Inspect and Repair Wiring

Sub-step 1: Remove the fuse box cover and locate the affected circuit.
Sub-step 2: Visually inspect wiring for any frays, cuts, or signs of wear. Repair any damaged wiring by splicing in new wire using wire strippers and connectors.
Sub-step 3: Clean any corrosion from connectors using electrical contact cleaner.

3. Test Components

Sub-step 1: Reconnect any components disconnected during diagnostics.
Sub-step 2: Reconnect the battery and replace the blown fuse with a new one of the correct amperage.
Sub-step 3: Test the circuit for proper operation. Monitor if the new fuse blows immediately or if components function correctly.

4. Secure Connections

Sub-step 1: Once the circuit is confirmed to be operational, secure all wiring and connectors with electrical tape to prevent future issues.
Sub-step 2: Reinstall the fuse box cover and ensure it is securely fastened.
