Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, flathead screwdriver.
Disconnect the vehicle battery to ensure safety during repairs.

2. Check and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the power windows using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; if blown, replace it with a fuse of the same amperage.
Reconnect the battery and test the power windows.

3. Test and Replace Window Switches

Remove the door panel using a socket set and flathead screwdriver to access the switches.
Disconnect the electrical connector from the switch.
Use a multimeter to check for continuity across the switch terminals.
If defective, replace with a new switch and reassemble the door panel.

4. Inspect and Repair Wiring

Visually inspect the wiring harness and connectors for any signs of fraying, breaking, or corrosion.
Repair or replace any damaged sections of wire.
Ensure all connections are secure and free of corrosion before reassembling.

5. Test the Window Motor

Disconnect the window motor connector.
Use a multimeter to check for power at the connector while pressing the window switch.
If no power is present, trace the wiring back to the fuse box or switch for faults.
If power is present but the motor does not operate, replace the window motor.
