Solution

1. Preparation

Gather tools including a multimeter, socket set, and screwdriver.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box and identify the fuse related to the power windows.
Remove the fuse and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Test Window Switches

Remove the door panel to access the power window switches.
Disconnect the switch connector and use a multimeter to check for continuity.
Replace the switch if it does not show continuity.

4. Inspect Wiring and Connectors

Carefully inspect the wiring harness for frayed wires or loose connections.
Repair any damaged wiring and ensure all connectors are securely attached.

5. Test Window Motors

Disconnect the window motor from the harness.
Using jumper wires, connect the motor directly to the battery to test if it operates.
Replace the window motor if it does not function when directly powered.

6. Reprogram Door Control Module (if necessary)

Use a diagnostic tool to reset and reprogram the door control module if there are any faults detected.
Follow the manufacturer's specific programming instructions.
