Solution

1. Preparation

Ensure the vehicle is parked safely and the ignition is turned off.
Disconnect the negative terminal of the battery to prevent electrical shock.

Tools Required:

Multimeter
Socket set
Screwdriver set
Wire strippers/crimpers

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power window using the owner's manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Inspect and Replace the Window Switch

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the wiring harness from the window switch.
Use a multimeter to test the switch for continuity.
If defective, replace the switch with a new one and reconnect the harness.

4. Test and Replace the Window Motor

If the switch is functional, check the window motor.
Remove the door panel to access the window motor.
Disconnect the motor's wiring harness.
Use a multimeter to test the motor for power when the switch is activated.
If no power is reaching the motor, trace the wiring back for damage.
If the motor is defective, remove it by unscrewing the mounting bolts and replace it with a new motor.

5. Reassemble the Door Panel

Once repairs are completed, reconnect all wiring harnesses.
Reattach the door panel and ensure all clips and screws are securely fastened.

6. Final Check

Reconnect the negative terminal of the battery.
Test the power window to ensure it operates correctly.
