Solution

1. Preparation

Gather tools and parts needed.
Disconnect the negative battery cable to prevent electrical shorts.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse (refer to the owner's manual).
Remove the fuse and inspect it for continuity. Replace it if it's blown with a fuse of the same amperage.

3. Test Power Window Switches

Tools Required: Multimeter
Reconnect the battery cable.
Remove the switch panel to access the power window switches.
Use a multimeter to test for continuity at the switch terminals while pressing the switch.
If there's no continuity, replace the switch.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the window motors and switches.
Look for frayed wires or loose connections.
Repair or replace any damaged wiring or connectors.

5. Check Window Motor Operation

Tools Required: 12V power source or jumper wires
Disconnect the window motor connector.
Use jumper wires to apply direct voltage to the motor terminals to see if the motor operates.
If the motor does not work with direct power, replace the motor.
