Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuse puller.
Disconnect the negative battery terminal to ensure safety.
Gather necessary parts based on diagnostic findings.

2. Battery and Charging System Check

Sub-steps:
1. Use a multimeter to measure the battery voltage; it should be around 12.6 volts when fully charged.
2. Start the vehicle and measure the voltage again; it should read between 13.7 to 14.7 volts to confirm the alternator is charging correctly.
3. If voltage is low, replace the battery or alternator as necessary.

3. Fuse Inspection and Replacement

Sub-steps:
1. Identify the fuse box location and remove the cover.
2. Use a fuse puller to check for blown fuses related to the malfunctioning systems.
3. Replace any blown fuses with new ones of the same amperage.

4. Wiring and Connector Inspection

Sub-steps:
1. Visually inspect wiring harnesses for any signs of wear, fraying, or damage.
2. Check all connectors for corrosion or loose connections and clean or repair as necessary.
3. Secure any loose wires to prevent further issues.

5. Component Functionality Test

Sub-steps:
1. For power windows and locks, use the vehicle’s switch to test each window and lock individually.
2. If a component fails, proceed to remove the door panel for inspection and replacement of the motor or switch as needed.
