What is the reason for the malfunction of the one-touch window lift on the driver's side of the Lavida?
3 Answers
The possible causes for the failure of the one-touch window lift are as follows: 1. Switch assembly: Internal failure of the driver's side window regulator switch assembly. 2. Wiring harness: Damage or moisture in the wiring harness between the switch and the body control module. 3. Body control module: Internal failure of the body control module. Additional relevant information: Solution: The issue may lie in the power window switch group or seat adjustment switch group, or their wiring. Measure whether the cabin control module is supplying power to the switch group. If the wiring and switch group are not open-circuited, it can be determined that the cabin control module is damaged. Replace the cabin control module and test whether the driver's side window lift and seat adjustment function properly.
Recently, I encountered an issue with the one-touch up/down function failing on the driver's side window of my Lavida, which was quite annoying. There could be several possible reasons for this. First, the switch button might be faulty, such as internal contact wear or getting stuck; when I checked, the button didn’t respond when pressed, though manual operation sometimes still worked. Second, the window motor might be damaged—over time, the internal coils can age or the gears may slip, causing the one-touch function to fail. Another possibility is a wiring issue, including poor contact or a short circuit, especially in areas where the wires bend inside the door. A common culprit is also a blown fuse, located in the car’s fuse box, which can burn out due to excessive current. For safety, I’d first try manually raising or lowering the window all the way and holding the button for a few seconds to reset it. If that doesn’t work, it’s best to take it to a professional shop for inspection rather than attempting risky DIY fixes that could lead to electric shock.
I've been driving a Lavida for several years, and the one-touch up/down function for the driver's window often malfunctions. There are several main reasons to watch out for. The switch button is prone to failure, with internal spring plates aging or getting stuck due to dust; my car started having intermittent issues last month, but manual operation still works. Circuit problems are also common, such as loose wire connections or blown fuses, which can cause unstable current and disable the one-touch function; remember to check the fuse box location and avoid using the wrong fuse type. The window motor might also be problematic, with worn-out gears or sticky rails causing the glass to get stuck. Avoid holding the button down for too long during daily use to prevent premature wear, and it's recommended to inspect and clean/lubricate the door components every six months. Getting it checked at a 4S shop is more reliable.
