What are the reasons for the complete failure of the Lavida electric windows?

Lavida electric windows complete failure reasons include the system temporarily disabling the lifting function, damage to the window regulator, malfunction of the window control button, etc. System temporarily disabling the function: After raising and lowering the window glass several times in a row, to prevent damage from overheating of the window lift motor, the window glass lifting function may be temporarily disabled for a few seconds. You can wait for the function to recover before operating again. Window regulator damage: Try using the car key to control the window lifting. If the car key also cannot control it, it means the car window regulator is damaged and needs repair. Window control button malfunction: The window control button is unresponsive or there is a wiring issue. Check the wiring of the driver's side window switch. If the wiring is fine, the switch needs to be replaced.
The most common issue causing all power windows in the Lavida to malfunction is either a blown main fuse or a faulty master switch on the driver's side. I've seen this several times during repairs - since the driver's side switch controls all windows, when it fails, the entire system goes down. Another possibility is relay failure; relays manage current transmission and can cut power when their contacts oxidize. Wiring shorts or breaks are also frequent, especially during humid weather when corrosion occurs more easily. I'd recommend first checking the fuse box and trying to replace the corresponding fuse. If you hear a faint motor sound but the window doesn't move, the motor might be jammed or have loose wiring. Don't attempt to disassemble circuit boards yourself - it's safest to take it to a 4S shop for professional diagnosis with testing equipment to avoid potentially bigger problems.
I've been driving a Lavida for ten years, and recently encountered the frustrating issue of all windows malfunctioning. The cause was moisture infiltration into the wiring during rainy weather, leading to simultaneous short circuits in several window control modules. First, I confirmed the battery had sufficient charge, then checked that the fuses were intact, but found the main relay was burnt out. Replacing it with a spare relay solved the problem. Aging wiring is also a potential hazard, as the Lavida model often has issues in humid areas. Another possibility is a fault in the bus control unit—it's the brain of the system, and if it fails, everything stops working. If you face this situation, don't panic; try turning off the engine and restarting—sometimes the electronic system resets and recovers. It's advisable to regularly maintain and inspect connectors to prevent sudden failures that could compromise driving safety.
