Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is parked on a level surface and powered off.
Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.

2. Inspect and Replace Window Switches

Sub-steps:
1. Remove the door panel using a socket set and screwdriver to gain access to the switches.
2. Disconnect the wiring harness from the window switch.
3. Test the switch with a multimeter for continuity; replace if defective.
4. Reconnect the new switch and secure the door panel back in place.

3. Test and Replace Window Motor

Sub-steps:
1. If switches are functional, access the window motor by removing the door panel completely.
2. Disconnect the motor from the wiring harness.
3. Connect a multimeter to the motor connector and activate the switch to check for voltage.
4. If no voltage is detected, check the wiring and fuse. If voltage is present, replace the window motor.
5. Install the new motor, reattach the window regulator, and ensure all components are secured.

4. Reassemble and Test

Sub-steps:
1. Reassemble the door panel and secure it with screws.
