Solution

1. Preparation

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

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the power window fuse (refer to the owner's manual for the correct fuse location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse and replace it if it is blown (look for a broken wire inside the fuse).
Reinstall the fuse and reconnect the battery.

3. Replace Power Window Switch

Remove the door panel using a socket set to access the screws and clips.
Carefully pry off the switch panel from the door to access the power window switch.
Disconnect the wiring harness from the power window switch.
Replace the switch with a new one and reconnect the wiring harness.
Reassemble the door panel and ensure all clips and screws are secured.

4. Inspect and Replace Window Motor (if necessary)

If the switch replacement does not resolve the issue, proceed to check the window motor.
Ensure the door panel is removed as per step 3.
Disconnect the wiring harness from the window motor.
Using a multimeter, check for voltage at the motor connector when the switch is pressed.
If no voltage is present, the issue may lie with the switch or wiring. If voltage is present, remove the motor by unscrewing the mounting screws.
Install the new window motor and reconnect the wiring harness.
