Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked safely with the ignition off.
Disconnect the battery to prevent electrical shock.

2. Fuse Inspection

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the cover and find the power window fuse using the diagram on the fuse box cover.
Pull the fuse using a fuse puller or pliers and inspect it for continuity.
If blown, replace it with a fuse of the same amperage.

3. Switch Testing

Reconnect the battery and test the power window switches.
Use a multimeter to check for continuity when the switch is pressed.
If no continuity is present, replace the faulty switch.

4. Motor and Wiring Check

If the switch is functional, remove the door panel to access the window motor.
Inspect the wiring harness for any signs of wear or disconnection.
Use a multimeter to check for voltage at the motor connector while pressing the switch.
If voltage is present but the motor doesn’t operate, the motor may need replacement.

5. Motor Replacement

If necessary, disconnect the power window motor from the wiring harness.
Remove the motor by unscrewing the mounting bolts (note their torque specifications if available).
Install the new motor by reversing the removal steps and ensuring it is securely mounted.
Reconnect the wiring harness to the new motor.

6. Reassemble and Test

Reattach the door panel, ensuring all clips and screws are secure.
Reconnect the battery and test the windows for proper operation.
