What is the reason for the failure of three windows in BYD S6?
3 Answers
The reasons for the failure of three windows in BYD S6 are as follows: 1. Damage to the window glass regulator: The car window regulator is a door accessory in the door system that realizes the lifting and lowering movement of the door glass. It is a special component for adjusting the opening size of the door window. Its function is to ensure the smooth lifting and lowering of the door window glass and its smooth opening and closing. If it is damaged due to aging or impact, the window glass regulator needs to be replaced. 2. The window is stuck by foreign objects: The aging of the glass sealing strip increases the resistance to lifting. If the glass guide rail is stuck with foreign objects or is too dirty, it will also cause the window to fail to lift or lower. Clean the guide rail and apply lubrication, and replace the car's sealing strip at the same time.
I also encountered the issue of three windows failing simultaneously when I first drove my BYD S6, which was quite frustrating. The likely cause is a blown main switch or master fuse, since these three windows are managed by a single control point, not just individual motor failures. You should first check the fuse box, typically located under the driver's seat or in the engine compartment. Open the cover, find the fuse labeled 'window' or 'power window,' and check for any signs of melting. If it's blown, buy a replacement with the same amperage from an auto parts store and try swapping it. Additionally, aging wiring or poor contact could also be the culprit, especially during rainy weather when short circuits are more likely. For safety, if you can't handle it yourself, take it to a repair shop immediately—being unable to open windows in an emergency is dangerous. Regular simple checks, like cleaning switches and connection points, can help prevent such issues.
As an experienced DIYer who frequently works on older cars, I've encountered many cases of three windows not working in the S6. The most common causes are either a faulty main control module or fuse issues. First, try restarting the car: turn off the engine, remove the key, wait a few minutes, and then restart. Sometimes electronic systems just need a reboot to function properly. If that doesn't work, check whether the master window switch on the driver's side is malfunctioning, as it serves as the "control hub" for all three windows. Regarding fuses, inspect positions F10 or F12 in the interior fuse box to see if they're blown. If the fuses are intact, there might be a wiring short circuit - damaged wire insulation can cause serious issues. While you could remove the switch cover and test current with a knife, make sure to take proper safety precautions. Don't force it; it's better to visit a professional shop where they can use a multimeter for diagnosis. BYD vehicles have sensitive electronic systems, so getting it fixed early will save you headaches.
