Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Locate the fuse box and identify the fuse for the power windows.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown with a new fuse of the same amperage.
Reconnect the battery and test the power windows.

3. Test and Replace the Window Switch

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the wiring harness from the window switch.
Use a multimeter to check for continuity; replace the switch if it is faulty.
Reassemble the door panel after replacing the switch.

4. Inspect and Replace the Window Motor

If the switch is functional, locate the power window motor within the door.
Disconnect the wiring harness from the motor.
Test the motor by applying direct battery voltage to it; if it doesn’t work, replace the motor.
Remove the old motor by unscrewing it from the door and install the new motor.
Reconnect everything and test the window operation.

5. Clean and Lubricate Window Tracks

Inspect the window tracks and ensure they are free from debris.
Clean the tracks with a suitable cleaner and lubricate them with silicone spray.
Test the windows again to ensure smooth operation.
