Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, wire strippers, electrical tape, fuses.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Battery and Connections Inspection

Visually inspect the battery terminals for corrosion. Clean with a mixture of baking soda and water if necessary.
Tighten terminals securely. Check and clean cable connections using a wire brush.

3. Fuse Inspection and Replacement

Locate the fuse box as per the owner's manual.
Remove the fuses related to malfunctioning systems using a fuse puller.
Inspect each fuse; replace any that appear blown with the same amperage rating.

4. Voltage and Current Testing

Reconnect the battery and set the multimeter to DC voltage.
Measure the voltage across the battery terminals; it should read around 12.6 volts when fully charged.
Check voltage at the components showing issues (e.g., windows, locks). If the voltage is low, trace back to the source.

5. Wiring Harness Examination

Visually inspect wiring harnesses for any visible damage or wear.
If damage is found, use wire strippers to remove the damaged section, and splice in new wire of the same gauge. Secure with electrical tape.

6. Ground Connection Verification

Locate all ground points in the vehicle, usually near the battery and engine block.
Remove ground connections, clean them, and reattach securely.
