What could be the reason for the inability to raise or lower the windows on three doors of a seventh-generation Accord?

The inability to raise or lower the windows on three doors of a seventh-generation Accord may be due to the vehicle's master window switch not being activated or issues with the window regulator control module. Below is relevant information about automotive window regulators: 1. Classification: Window regulators are the mechanisms for raising and lowering car door windows, mainly divided into two categories: electric window regulators and manual window regulators. Nowadays, many car door windows use push-button electric mechanisms, employing electric window regulators. 2. Electric Window Regulators: Electric window regulators in cars typically consist of a motor, reducer, guide rope, guide plate, and window mounting bracket. The master switch is controlled by the driver to open or close all door windows, while individual switches on each door handle allow separate control of each window, making operation very convenient.
I've driven several cars and encountered multiple instances where the windows wouldn't roll up or down. There are usually a few common causes. The most frequent issue is a faulty master switch module. For example, in the design of the seventh-generation Accord, the master control switch manages three windows, and if it fails, all windows may stop working. Another common problem is a blown fuse, especially the main fuse or circuit protector, as aging wiring harnesses in older cars can easily cause short circuits. A malfunctioning door control unit is also a possibility, particularly in older Accords where the circuit board inside the module may get damp or corroded. Additionally, wiring harness damage around the door hinges is quite common, as repeated opening and closing can wear out and break the wires. It's advisable to start with the simplest checks: inspect the corresponding fuse in the fuse box to see if it's intact, then try pressing the individual switch on the passenger door. If there's still no response, it's best to have a professional inspect the electrical system as soon as possible. Avoid dismantling things yourself to prevent safety risks.
My old car had a similar issue before, with three windows malfunctioning simultaneously. Back then, I suspected a shared circuit fault. The main window switch assembly in the seventh-generation Accord is prone to aging, especially with poor button contact or internal wiring breaks, which can affect all door operations. Weather factors should not be overlooked either, as rainwater intrusion can cause the switch module to become damp or corroded. Another possibility is a loose or broken common ground wire between the doors, which would cut off the power supply. The inspection method is quite simple: first, check the fuse box near the driver's seat, locate the fuses labeled 'window,' and replace them if they're blown. If that doesn't work, it might be that the control module needs a reset. For regular maintenance, I recommend periodically cleaning the window tracks to avoid dust buildup that increases the switch load.
