why does my Volkswagen Golf MK7 (2015-2019) keep blowing fuses

Solution

1. Preparation

• Gather tools and materials: multimeter, OBD-II scanner, socket set, screwdrivers, and replacement fuses.
• Disconnect the vehicle battery to prevent electrical shock or further damage during the repair process.

2. Inspect and Clean Fuse Box

• Remove the fuse box cover using a screwdriver.
• Inspect the fuse box for corrosion or damage. Clean any corrosion with a contact cleaner and a soft brush.
• Replace any damaged fuses with the correct amperage rating.

3. Wiring Inspection

• Examine the wiring harnesses for the circuits associated with the blown fuses.
• Look for frayed wires, exposed conductors, or signs of shorts. Repair or replace damaged wiring as necessary.
• Ensure connectors are secure and not corroded. Clean and secure any loose connections.

4. Component Testing

• Use a multimeter to test the electrical components associated with the blown fuses for proper operation.
• Replace any faulty components (e.g., switches, motors) that are causing a short circuit or drawing excessive current.

5. Reassemble and Test

• Reinstall the fuse box cover securely.
• Reconnect the battery and replace any blown fuses.
• Start the vehicle and test all electrical components to ensure they are functioning correctly.
