Solution

1. Preparation

Tools Required: None specifically required for preparation.
Ensure the vehicle is in park and powered on.
Disconnect the battery if any electrical repairs are anticipated.

2. Inspect Window Lock Switch

Sub-steps:
- Locate the window lock switch on the driver's side door.
- Ensure it is in the "off" position.
- Test the window functions again.

3. Check Fuse and Wiring

Sub-steps:
- Access the fuse box (refer to the owner’s manual for location).
- Inspect the fuse associated with window motors for continuity.
- If blown, replace with a fuse of the same amperage.
- Visually inspect wiring to window motors for signs of damage or disconnection.

4. Inspect Window Motor and Switch

Sub-steps:
- Remove the door panel using a trim removal tool.
- Disconnect the power connector from the window motor.
- Test the motor directly with a multimeter to check for voltage when the switch is activated.
- If no voltage is present, further inspect the switch for faults.
- If the motor is faulty, replace it with a new unit.

5. Reassemble Components

Sub-steps:
- Once repairs are completed, reattach the window motor connector.
- Reinstall the door panel, ensuring all clips are secured.
- Test the window operation before fully tightening screws.
