Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Check the power window fuse for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage (refer to the owner's manual for specifications).

3. Test and Replace Window Switches

If fuses are intact, remove the door panel to access the window switches.
Disconnect the switch connectors and test for continuity with a multimeter.
If faulty, replace the window switch with a new one, ensuring proper connection.

4. Check Window Motor Functionality

If switches are functioning, access the window motor by removing the door panel.
Disconnect the motor connector and apply 12V directly from a battery to test the motor.
If the motor does not operate, replace it with a new motor.

5. Reassemble Door Panel

Reattach the door panel carefully, ensuring no wires are pinched.
Replace screws and clips used to secure the panel.
Reconnect the negative battery terminal once everything is reassembled.
