Solution

1. Preparation

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

Tools Required:

Socket set
Multimeter
Screwdrivers (flathead and Phillips)
OBD-II scanner

2. Replace the Power Window Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the fuse for the power windows (consult the owner’s manual for the exact location).
Remove the fuse with a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown with a fuse of the same amperage.

3. Inspect and Replace the Power Window Switch

Remove the door panel using a screwdriver and prying tool.
Disconnect the switch connector from the door panel.
Test the switch for continuity with a multimeter; replace it if faulty.
Reconnect the new switch and reassemble the door panel.

4. Test and Replace the Power Window Motor

If the switch is functional, access the window motor by removing the door panel.
Disconnect the motor connector.
Use the multimeter to check for voltage at the motor connector when the switch is pressed; if there is power, the motor is defective.
Replace the motor by removing the retaining screws and installing the new unit in the reverse order.
