Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is in a safe environment to work on, preferably a garage or a flat surface.

2. Check and Replace Fuse

Locate the fuse box; refer to the owner's manual for the exact location.
Remove the power window fuse using a fuse puller.
Inspect the fuse for continuity; replace it if blown with the same amperage rating.

3. Inspect and Replace Window Switch

Remove the door panel using a screwdriver and trim tools to access the window switch.
Detach the electrical connector from the switch and check for voltage using a multimeter.
If no voltage is present, replace the window switch with a new part.

4. Test and Replace Window Motor

If the switch is functioning, locate the window motor in the door assembly.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the motor terminals; if no voltage is detected, the issue may be upstream.
If voltage is present, apply direct power to the motor from a separate battery.
If the motor does not operate, replace it with a new motor.

5. Reassemble and Test

Reconnect any electrical connectors and reassemble the door panel.
Reconnect the negative battery terminal.
Test the power windows for proper operation.
