Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and wire connectors.
Disconnect the negative battery terminal to ensure safety while working with electrical components.

2. Check and Replace Fuse

Locate the fuse panel: Refer to the owner’s manual to find the fuse panel location.
Remove the fuse: Use a fuse puller or pliers to extract the power window fuse.
Inspect the fuse: Check for a broken filament.
Replace if necessary: Install a new fuse with the same amperage rating (typically 30A).

3. Test the Power Window Relay

Locate the relay: Find the power window relay in the fuse panel.
Remove the relay: Pull it straight out from its socket.
Test with multimeter: Set the multimeter to continuity mode. Check the relay terminals for continuity while toggling the switch.
Replace if faulty: Install a new relay if continuity is not present.

4. Inspect and Test the Window Switch

Remove the door panel: Use a flathead screwdriver to gently pry off the panel and access the switch.
Disconnect the switch connector: Pull apart the connector carefully.
Test the switch: Use a multimeter to check for continuity across the switch terminals when pressed. Replace the switch if it fails the test.

5. Test the Window Motor

Access the window motor: If necessary, remove the door panel to reach the motor.
Disconnect the motor connector: Carefully pull the connector off the motor.
Apply direct voltage: Use jumper wires to connect the motor directly to the battery (positive to positive, negative to negative).
Listen for operation: If the motor operates, it is functioning correctly; if not, replace the motor.
