Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and needle-nose pliers.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box; refer to the owner's manual for the exact location of the power window fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity using a multimeter; replace if blown.
Reinstall the new fuse and reconnect the battery.

3. Test Window Switch

Remove the door panel using a flathead screwdriver to pry off clips.
Disconnect the window switch connector.
Use a multimeter to check for continuity in the switch when activated.
If faulty, replace the window switch with a new one.

4. Test Power Window Motor

Access the power window motor by removing the door panel.
Disconnect the motor harness.
Apply 12V directly to the motor terminals using jumper wires to see if it operates.
If the motor does not respond, replace the motor.

5. Check Wiring and Control Module

Inspect the wiring harness for any visible damage, fraying, or loose connections.
If wiring appears intact, access the door control module.
Check connections and ensure no corrosion is present.
If the module is faulty, replace it.
