What causes the BYD S6 power window failure?

[McGavin]

BYD S6 power window failure occurs when the vehicle's body control module loses the data signal from the remote key for window control. Here are specific details about the one-touch window function: 1. Operation method: Press and hold the switch until the window reaches the desired position, then release to stop movement. Vehicles with one-touch windows have two-stage control switches - the first position operates like regular power windows, while the second position (when pressed and released) automatically fully opens or closes the window. 2. Function purpose: This feature, commonly found in mid-to-high-end models, provides convenience for occupants and enhances safety by preventing driver distraction during window operation. 3. Anti-pinch protection: One-touch windows typically include anti-pinch functionality to prevent injury. The driver-side window prioritizes this safety feature with exclusive one-touch control.

A while ago, my S6's passenger window had the same issue, and it took me a long time to figure it out. The most common problem is poor contact in the small switch inside the door—pressing it doesn't respond or it works intermittently, especially after rain. Another issue could be with the window regulator motor; over time, the carbon brushes wear out, and if the motor can't turn, the window naturally gets stuck. A frequently overlooked cause is a loose wiring connector near the door hinge—the wiring harness bends repeatedly when opening and closing the door, leading to poor connections. I suggest checking if other windows work normally first. If only one window isn't moving, it's likely a separate control module or a deformed/track jam. For such mechanical issues, it's best not to force it—take it to a repair shop for a proper inspection.

Having driven an S6 for several years, I know all too well about window malfunctions. First, suspect the window regulator switch—old cars often have oxidized contacts, and a spray of WD-40 might fix it. If you hear the motor humming but the glass won't move, it's likely the nylon cord in the glass track has snapped. If the issue arises on rainy days, chances are the wiring harness's waterproof sleeve has cracked, letting water in and causing a short circuit. A word of caution: when the auto window function suddenly fails, don't keep pressing the button—it can easily blow the $3-4 window fuse. If you're tackling it yourself, start by removing the door panel to check the connectors. If you see green corrosion on the wires, it's time to replace the entire wiring harness.

I've studied quite a few BYD window malfunction cases, and there are typically four possibilities: First, poor contact in the window switch module due to dust accumulation on the contacts; Second, a burned-out window motor or jammed gears; Third, deformed glass guide rails causing excessive resistance; Fourth, internal wire breakage in the door panel harness from repeated folding. There's a simple troubleshooting method: simultaneously press and hold the window switch's up and down buttons for ten seconds to reset the control system. If the reset doesn't work, you might need to replace the entire window regulator assembly, which costs around 300 yuan. Regularly keeping the window seal strips clean can help reduce failure rates.

Last time when I sent my S6 for repair, the technician taught me a few diagnostic methods: When the window fails to go up or down, first listen for sounds. If there's a buzzing sound from the motor, it indicates the circuit is functioning properly, and the issue lies with the lifting bracket; if there's no sound at all, focus on checking the fuse and the switch. Also, check if all the windows are not working—if it's just one window, it's often a problem with the window regulator. Common causes include deformed tracks or aged and cracked nylon sliders. If you're doing it yourself, you can try removing the door panel to check if the cable has come off, but if you're inexperienced, don't tamper with the motor wiring harness—reversing the connector can burn out the control board. Remember to regularly spray rubber lubricant to protect the tracks.
