Solution

1. Preparation

Gather all necessary tools and replacement parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Ensure you have a clean workspace and proper lighting.

2. Replace the Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the windows again.

3. Replace Power Window Switch

If the fuse is intact, remove the door panel where the switch is located using a socket set.
Disconnect the switch wiring harness by unclipping it.
Install the new power window switch by connecting the wiring harness and securing it in place.
Reassemble the door panel and test the window operation.

4. Replace Power Window Motor (if necessary)

If the switch replacement does not resolve the issue, access the window motor by removing the door panel.
Disconnect the wiring harness from the window motor.
Unbolt the motor from the regulator assembly and carefully remove it.
Install the new power window motor, securing it with bolts and reconnecting the wiring harness.
Reassemble the door panel and check the functionality.

5. Check Window Regulator (if necessary)

If the motor and switches are functional but the window does not move, inspect the window regulator.
Remove any obstructions or debris that may be blocking the window's path.
If the regulator is damaged, it may need to be replaced. Follow similar steps as for the motor to remove and replace the regulator.
