How to Set One-Touch Up/Down for Windows on LaCrosse?

[VonRachel]

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.

When I first learned to set the one-touch up/down feature for the Buick LaCrosse windows, I was young and had to search online for tutorials before realizing how easy it was. I'd start by lowering the window completely, then press and hold the up button until the window reached the top, keeping the button pressed for a few seconds to let the system memorize the position. After testing the one-touch up function, I'd repeat the process for one-touch down: raise the window fully, then press and hold the down button until it reached the bottom, maintaining pressure for several seconds. No tools are needed - you can do it right from the driver's seat. Though once in winter, I encountered sticky buttons and had to lubricate the window tracks. As someone who frequently takes long drives, I find one-touch operation saves time and effort, plus allows quick window closure during roadside emergencies for security. Developing the habit of checking this feature is quite practical.

When it comes to the one-touch window up/down setting, I'll explain the basic principle: the system needs to learn a reference position. Typically, I fully lower the window to ensure there's no obstruction, then hold the up button until it reaches the top and maintain for about 5 seconds, allowing the module to memorize the upward stroke. The same applies to setting the down function: after raising to the top, hold the down button until it reaches the bottom for the same duration. For LaCrosse models experiencing initialization failure, first disconnect the battery for a few minutes before retrying. Relatedly, I pay attention to voltage stability, as alternator issues can cause memory failure. After these simple operations, test the function for smooth operation to confirm success.
