What to do if three windows of BYD S6 malfunction?
2 Answers
If three windows of BYD S6 malfunction, lift the window button directly to raise the window to the top, hold for 3-5 seconds and then release. Then press the window button to lower the window to the bottom, hold for 3-5 seconds and release. Here is more information about BYD: 1. BYD is a Chinese automobile brand founded in 1995, mainly producing commercial cars, family cars, and batteries. 2. Representative models of BYD include traditional high-quality fuel vehicles such as F3, F3R, F6, F0, G3, G3R, L3/G6, and Surui, the S8 sports hardtop convertible, the high-end SUV model S6 and MPV model M6, as well as the globally leading F3DM, F6DM dual-mode electric vehicles and the pure electric vehicle E6.
When I see all three windows of the BYD S6 malfunctioning simultaneously, the issue usually lies in the shared control system. It's highly unlikely that all three motors fail independently since they operate separately; instead, common culprits include master control components such as fuses, the main switch module, or circuit faults. Checking the fuse is the easiest first step—open the hood, locate the fuse box, and refer to the manual to find the window fuse (typically 10A or 15A). If it's blown, try replacing it. If that doesn’t work, the master window switch on the driver’s side may be faulty, with oxidized contacts or water-induced short circuits—splashing water during car washes is a common cause. Additionally, aging wiring or relay failures can disrupt power supply. It’s best to visit a 4S shop or professional repair center immediately for diagnosis, as they can use scanners to read fault codes for precise troubleshooting. Safety-wise, don’t take risks—ensure backup ventilation methods like the AC defogger are ready while driving.
