What causes a Lavida's window to fail to roll up or down?
2 Answers
There are several reasons why a Lavida's window may fail to roll up or down: Poor contact in the electronic control wiring harness: If you notice a burning smell or hear unusual noises from the door panel when holding down the window button for an extended period, it's highly likely that the window lift motor components are damaged. In such cases, it's recommended to directly visit a 4S shop or auto repair shop to replace the window lift motor. Motor overheating protection: To protect the power supply circuit, window lift motors generally have an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window to stop functioning. In this situation, simply wait for the motor to cool down.
Last time, the left rear window of my Lavida suddenly got stuck. Upon disassembly, I found the window regulator cable had snapped. This component in Volkswagen models is quite delicate, especially when the windows are operated frequently—the steel cables are prone to deformation and breakage. Here's a diagnostic tip: Listen for the motor sound when pressing the button. If you hear it, the motor and switch are likely functioning properly, and there's an 80-90% chance the issue is either the cable derailing or the plastic slider breaking. In my older car, I've also encountered aged glass guide rubber seals causing the window to freeze and stick after rain. In emergencies, you can gently lift the window edge upwards while pinching it—a clicking sound indicates temporary realignment. If replacing the regulator yourself, be cautious with the door panel clips; damaging even one can lead to rattles. For those less skilled in DIY repairs, it's better to visit a specialized repair shop—labor costs for disassembly and installation are around 200 yuan.
