Solution

1. Preparation

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

2. Check and Replace Fuse

Locate the fuse box, typically under the dashboard or hood.
Remove the power window fuse using a fuse puller.
Inspect the fuse; if blown, replace it with the same amperage rating (check owner's manual).
Reconnect the battery and test the window operation.

3. Test and Replace Window Switch

Remove the door panel using a socket set and trim removal tools.
Disconnect the power window switch connector.
Use a multimeter to check for continuity on the switch terminals.
If faulty, replace the switch with a new one.
Reassemble the door panel and reconnect the battery.

4. Inspect and Replace Window Motor (if necessary)

With the door panel accessed, locate the window motor.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the motor connector when the switch is activated.
If no voltage is present, further electrical diagnostics may be needed.
If the motor is faulty, remove it by unscrewing it from the regulator assembly and replacing it with a new one.
Reassemble the door panel and reconnect the battery.
