Why can't the car windows automatically roll up and down after replacing the battery?

After replacing the car battery, the windows cannot automatically roll up and down because the power interruption during the battery replacement process causes memory loss. After replacing the battery, it needs to be recalibrated. Here are the relevant details: 1. Reset method: Turn the key to power on, pull and hold the window-up button until the window reaches the top, then continue holding for 3 seconds to complete the automatic window-up function. Press and hold the window-down button until the window reaches the bottom, then continue holding for 3 seconds to complete the automatic window-down function. Repeat this operation for all four window buttons. 2. Introduction to automatic window operation: For regular power windows, you need to hold the switch until the window reaches the desired position, then release the button to stop the movement. Cars equipped with one-touch automatic windows have a two-stage window control switch. The first stage operates like regular power windows. The second stage allows the window to fully open or close automatically with a single press and release. This feature is designed for the convenience of passengers and drivers, primarily to prevent the driver from being distracted by operating the windows and to enhance safety.
After replacing the battery, the windows can't automatically go up and down. This is quite common because the system memory is lost after power disconnection, and the position needs to be manually reset. I suggest you try this method first: pull the window button to the highest position and hold it for more than 10 seconds to let it learn the position; then lower it to the lowest position and hold it for another 10 seconds. This way, the system can reset its memory. If it still doesn't work, the fuse might be blown or the wiring could be loose. Last time I encountered this, I fixed it myself and saved a hundred bucks, but if you handle it improperly and damage the window motor, it's a big loss. Remember, every time you replace the battery, it's best to do it without disconnecting the power or use a professional tool to assist, to prevent similar issues from recurring. Regularly checking the car battery terminals also helps prevent problems.
