Solution

1. Preparation

Gather Tools and Parts: Ensure all necessary tools and replacement parts are ready.
Safety Precautions: Disconnect the vehicle battery to avoid electrical shocks.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse related to the power windows (refer to the owner's manual for exact location).
Remove the fuse and inspect it for continuity. Replace it if blown.
Reconnect the battery and test the power windows.

3. Test Window Switches

Remove the switch panel from the door.
Use a multimeter to check for voltage at the switch when pressed.
- If there’s no voltage, proceed to check the wiring harness.
- If there's voltage, the switch may be faulty and should be replaced.

4. Inspect Wiring and Connectors

Remove the door panel to access the wiring harness.
Check for any visible damage, frays, or corrosion.
Clean or repair any damaged wiring and ensure all connectors are secure.

5. Test Power Window Motors

Connect a direct power source to the window motor leads (ensure to verify polarity).
If the motor operates, it may indicate the switch or wiring issue; if not, the motor may need replacement.

6. Replace Door Control Module (if necessary)

If all previous steps do not resolve the issue, consider replacing the door control module.
Disconnect the battery again, remove the module, and install the new one.
Reconnect the battery and test the power windows.
