Solution

1. Preparation

Tools Required: Multimeter, socket set, flathead screwdriver, Phillips screwdriver, wire stripper/crimper.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse using the vehicle's manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if blown, replace it with a new one of the same amperage.

3. Test and Replace Window Switch

Remove the door panel using a flathead screwdriver and Phillips screwdriver to access the window switch.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when the switch is activated.
If defective, replace with a new switch.

4. Check and Repair Wiring

Examine the wiring harness for any signs of damage, such as fraying or breaks.
If damaged, use wire strippers to remove the insulation from the wire ends and splice in new wire sections using crimp connectors.

5. Test Window Motor

Access the window motor by removing the door panel.
Disconnect the window motor's electrical connector.
Use jumper wires to connect the motor directly to the vehicle battery to test functionality.
If the motor does not operate, replace it with a new motor.

6. Reassemble Components

Reinstall the door panel and ensure all clips and screws are secure.
Reconnect the vehicle battery.
