Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Fuses

Sub-steps:
1. Locate the fuse box (typically under the dashboard or in the engine compartment).
2. Remove the cover and identify the fuse associated with the power windows (refer to the fuse diagram).
3. Pull the fuse using a fuse puller or pliers and visually inspect it for damage.
4. If blown, replace it with a new fuse of the same amperage rating.

3. Test Power Window Switches

Sub-steps:
1. Reconnect the battery and turn on the ignition.
2. Remove the door panel to access the power window switch.
3. Use a multimeter to check for continuity across the switch terminals while pressing the window button.
4. If there is no continuity, replace the power window switch.

4. Inspect Wiring and Connectors

Sub-steps:
1. Check the wiring harness connected to the power windows for any frayed or damaged wires.
2. Disconnect and inspect connectors for corrosion or loose connections.
3. Repair or replace any damaged wiring or connectors as necessary.

5. Test and Replace Window Motors

Sub-steps:
1. Remove the door panel to access the window motor.
2. Disconnect the motor wiring harness.
3. Use a jumper wire to supply power directly to the window motor to test its operation.
4. If the motor does not operate, replace it with a new window motor.
