Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse associated with the power windows (refer to the owner's manual).
Remove the suspected blown fuse and replace it with a new one of the same amperage.
Reconnect the battery and test the window operation.

3. Replace Faulty Window Switch

If the fuse is intact and the windows are still not functioning, remove the door panel to access the window switch.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity.
If faulty, replace with a new switch, reconnect the harness, and reassemble the door panel.

4. Check and Replace Window Motor

If the switch is operational, check the window motor. Access the motor by removing the door panel.
Disconnect the motor and apply direct battery power (positive to positive, negative to negative).
If the motor does not operate, replace it with a new unit.
Reassemble the door panel after replacing the motor.

5. Test Door Control Module

If all other components are functioning and the issue persists, check the door control module.
Ensure that it is properly connected to the wiring harness.
If necessary, replace the module with a compatible part and reprogram if needed.
