Solution

1. Preparation

Gather tools: Screwdriver set, multimeter, socket set, fuse puller.
Disconnect the vehicle battery to avoid electrical shorts.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller.
Inspect the fuse; if it's blown, replace it with a new fuse of the same amperage.

3. Inspect Window Switch

Remove the door panel using a screwdriver and socket set to access the window switch.
Disconnect the switch connector and inspect for corrosion or damage.
If necessary, replace the power window switch with a new one.

4. Test and Replace Window Motor

With the door panel removed, locate the window motor.
Disconnect the motor connector and use a multimeter to test for voltage when the switch is pressed.
If voltage is present but the motor doesn't operate, replace the window motor.
To replace, unbolt the motor from the window regulator and install the new motor.

5. Check Wiring Harness

Inspect the wiring harness for any wear, frayed wires, or disconnections.
Repair or replace any damaged wiring as needed.
