Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Fuses

Locate the fuse box, typically under the dashboard or engine compartment.
Identify the fuse for the power windows (refer to the owner's manual for exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.

3. Test and Replace Window Switches

Remove the door panel using a trim removal tool and socket set.
Disconnect the electrical connector from the window switch.
Test the switch with a multimeter for continuity.
If the switch is defective, replace it with a new switch, reconnect, and reassemble the door panel.

4. Inspect and Replace Window Motors

If the switches are functioning, proceed to check the window motors.
Disconnect the window motor from the wiring harness.
Test the motor directly by applying battery voltage to see if it operates.
If the motor is unresponsive, remove it from the door by unscrewing the mounting bolts.
Install a new window motor, reconnect the wiring, and secure the door panel.

5. Reassemble and Reconnect

Reattach the door panel, ensuring all clips and screws are secured.
Reconnect the battery once all repairs are complete.
