What causes the window to automatically roll down after being rolled up?
2 Answers
The window automatically rolls down after being rolled up, which is likely due to the activation of the anti-pinch function. You should check if the rubber seal is too dirty, causing increased resistance. Additionally, the window motor needs to be reset by rolling the window all the way up and holding the switch in the up position for 10 seconds. More details are as follows: 1. One-touch window operation refers to a system where the car window glass can be fully opened or closed with a single press of the button. Cars equipped with one-touch window operation have a two-stage window control switch. The first position works like a regular power window switch, while the second position allows the window to automatically fully open or close with a single press and release. 2. Nowadays, most mid-to-high-end models come with one-touch window operation, primarily for the convenience of drivers and passengers, avoiding distractions from manually operating the windows and improving safety. One-touch windows usually feature an "anti-pinch" function to prevent the risk of pinching fingers. Only the driver's window typically has one-touch operation. 3. Rear window lock switch: When this switch is pressed, it disables the window adjustment switches for the rear left and right windows and the passenger window, leaving only the driver's door switch operable. 4. Window switch: The window can be raised or lowered by pressing or pulling the switch.
It's quite annoying when the car window rolls up and then automatically rolls back down. I think there are several common reasons for this. One is the anti-pinch function at play - if your hand or an object is blocking the window track, the system will automatically lower the window for safety. Another possibility is improper window initialization; sometimes after power loss or system errors, the position needs to be reset. I've encountered motor issues before - aging motors or unstable power supply can cause abnormal window movement. Additionally, poor wiring connections can cause trouble; worn switches or relay failures may interrupt signals and trigger automatic lowering. Remember this problem occurs more frequently during rainy seasons - better get it checked at a professional shop promptly to avoid affecting driving safety.
