Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flat-head screwdriver.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the battery (negative terminal) to prevent electrical shocks.

2. Check and Replace Fuse

Locate the fuse box (usually found in the glove compartment or under the dashboard).
Refer to the fuse diagram in the owner's manual to identify the power window fuse.
Remove the fuse using a fuse puller or flat-head screwdriver.
Inspect the fuse for continuity; replace it if blown (use the same amperage fuse).

3. Inspect and Replace Window Switch

Remove the door panel using the socket set and screwdriver.
Disconnect the window switch connectors.
Test the switch with a multimeter for continuity when pressed.
If defective, replace the switch with an OEM part.

4. Check and Replace Window Motor

If the switch is functional, connect the multimeter to the motor harness.
If no voltage is present, inspect the wiring. If voltage is present, the motor is likely faulty.
Remove the window motor by unscrewing it from the window regulator assembly.
Install the new motor and secure it properly.

5. Reassemble and Test

Reconnect the door panel and ensure all clips and screws are secured.
Reconnect the battery.
Test the power window function to ensure it operates smoothly.
