What to Do When All Windows of a 2004 Passat Malfunction?

Should remove the inner cover and apply lubricant. If the glass cannot move at all, it may be a switch malfunction. If it's a switch issue, replacement is the only solution. If the electronic device is not functioning, checking the fuse is common practice. If the fuse is damaged, it is recommended to replace it. Dirt on the glass can also cause resistance, so it's important to keep the windows clean regularly.
As a seasoned Passat owner with years of experience, when all windows fail simultaneously, my first step is to check the fuse box. This 2004 model is prone to minor electrical glitches. The fuse location is under the dashboard on the driver's side—just flip open the cover and check the labels. If a fuse is blown, replacing it might solve the issue. If there's still no response, I then try resetting the car's system by turning off the engine and waiting a few minutes before restarting. Sometimes the malfunction is temporary and a reset does the trick. Also, don't overlook potential switch module problems—the Passat's window switches are known to age poorly, so ensure the buttons are securely connected. If all these checks yield no results, it's likely a wiring harness damage or motor failure, and professional diagnosis is needed. Regularly cleaning window tracks and lubricating seals can prevent jamming, especially for older cars like this that require diligent maintenance. Above all, avoid forcing the windows to prevent further component damage—safety comes first.
