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 (usually under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller.
Inspect the fuse for continuity; replace it if it’s blown with a new fuse of the same amperage.

3. Inspect and Replace Window Switch

Remove the door panel using a socket set to access the window switch.
Disconnect the window switch connector.
Test the switch with a multimeter for continuity. If faulty, replace with a new switch.
Reconnect the switch and reassemble the door panel.

4. Inspect and Replace Window Motor

If the switch is functioning, access the window motor by removing the door panel.
Disconnect the motor connector and test it with a multimeter for voltage when the switch is activated.
If no voltage is detected, check the wiring harness for damage.
If voltage is present but the motor does not operate, replace the window motor.

5. Reassemble Components

Once repairs are made, carefully reassemble the door panel.
Ensure all clips and screws are secured properly.
Reconnect the vehicle battery.
