Solution

1. Preparation

Tools Required:
- Screwdriver set
- Multimeter
- Torque wrench
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or hood.
Remove the cover and locate the power window fuse (refer to the fuse diagram).
Inspect the fuse for continuity; replace it if it is blown with a new fuse of the same amperage.

3. Inspect Window Control Switches

Remove the door panel using a screwdriver to access the control switches.
Disconnect the wiring harness from the switches.
Test the switches with a multimeter to ensure they are functioning correctly; replace if defective.

4. Test Window Motors

With the door panel removed, locate the window motor.
Disconnect the wiring harness from the motor.
Using a multimeter, check for voltage at the motor terminals while pressing the window switch.
If voltage is present but the motor does not operate, replace the window motor.

5. Reassemble and Test

Reconnect all wiring harnesses and reattach the door panel.
Reconnect the negative battery terminal.
Test the window operation from the driver’s side switch.
