Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the power window fuse.
Inspect the fuse visually; if it appears blown (broken filament), replace it with a new fuse of the same amperage.
Reinstall the fuse box cover and reconnect the negative battery terminal.

3. Replace Window Switch (if necessary)

Remove the door panel using a panel removal tool to access the window switch.
Disconnect the wiring harness from the switch.
Use a multimeter to test the continuity of the switch; if defective, replace it with a new switch.
Reconnect the wiring harness and reinstall the door panel.

4. Inspect and Replace Window Motor (if necessary)

If there is no voltage at the window motor from the switch, check the wiring harness for continuity.
If the wiring is intact and the switch operates correctly, replace the window motor.
Remove the door panel as previously described.
Disconnect the wiring harness from the window motor and remove the motor from its mounting.
Install the new window motor, reconnect the wiring harness, and reassemble the door panel.

5. Verify Body Control Module (if necessary)

If all components are functioning but the windows still do not operate, inspect the body control module.
Use an OBD-II scanner to check for any codes related to the window operation.
Follow the manufacturer’s guidelines to reset or reprogram the BCM if necessary.
