How to Set One-Touch Up/Down for Windows on LaCrosse?
2 Answers
Setting method for one-touch up/down windows on LaCrosse: Briefly press the window mechanical button to automatically lower the window completely; briefly pull the button to automatically raise the window fully; during the lowering process, release the long-pressed button to stop the window from descending; during the raising process, release the long-pulled button to halt the window's ascent. The LaCrosse is a new mid-to-high-end sedan introduced by Shanghai GM, with body dimensions of 5005mm in length, 1858mm in width, and 1500mm in height, and a wheelbase of 2837mm. In terms of exterior design, the LaCrosse features a massive three-dimensional shield emblem on the front, a wide chrome-plated front grille, and distinctive cannon-shaped taillights, presenting an overall appearance of grandeur and luxury.
To set the one-touch up/down feature for the Buick LaCrosse windows, I usually first check if my vehicle supports this function—most modern Buicks do. I sit in the driver's seat, roll the window all the way down, then press and hold the up button to raise the window to the top. After reaching the top, I continue holding the button for about 5 to 10 seconds until I hear a 'click' or see a small light flash, indicating the system has memorized the position. I then repeat a similar process to set the one-touch down feature: raise the window fully, press and hold the down button to the bottom, and hold for a few seconds. Note that this function may reset after a power disconnect, so occasional reprogramming is a good habit. Additionally, dirty or obstructed window seals may cause the one-touch feature to become less responsive, so I clean them regularly to prevent minor issues. Overall, the setup is simple and takes less than a minute, but I always remind myself to press the buttons gently to avoid damaging the motor.
