Through the driver's window lift switch. There are three types of window closers: 1. Time-controlled type: Requires disassembling the instrument panel under the original steering wheel and the driver's door panel to locate several related wires, including the original car window central locking trigger signal wire, power wires for the four window control motors, ground wire, relay return wire, etc., and then connecting them one by one with the relevant wires of the window closer; 2. Program-controlled type: The basic functions and control principles are largely similar to the time-controlled type. Due to the low price of microcontrollers, their memory capacity is small, generally within the range of 128-512 bytes, so the small capacity can only set some simple judgment levels. In practical applications, it is still relatively easy to cause misoperation, and the precision is not accurate enough; 3. Intelligent window closing system: Mainly through an electronic module, using the program set in the chip on the host to complete the detection function, the window closing steps are successfully completed. This product can detect the magnitude of the window lift resistance. When the window is closed, it interrupts the power supply, protecting the electric window motor from damage and also preventing the battery from being easily depleted.

As a frequent user of the 2021 Buick Excelle, I find the one-touch window-up feature incredibly practical—it helps me prevent water from entering the car during rainy days. The activation method is straightforward: First, sit in the car and ensure all doors are closed. You don’t need to start the engine, but it’s recommended to activate the feature after starting. Then, locate the window switch on the driver’s door panel, pull it to the highest position, and hold it for about 5 seconds until you hear a beep, indicating successful activation. Afterward, test it: When leaving the car, press and hold the lock button on the key fob, and the windows will automatically roll up; press and hold the unlock button to lower them. I learned this from the owner’s manual and have verified it multiple times. Common minor issues: If it occasionally malfunctions, restarting the vehicle or checking window initialization usually resolves it. Remember not to operate it while driving to avoid safety risks. It’s best to test the feature periodically to ensure stability. Once activated, one-touch window closing also deters thieves—super convenient!

I'm very familiar with the one-touch window operation for the 2021 Excelle's key. Every time I teach a newbie, I explain: After getting in the car and closing the door, start the engine or turn on the power. Then operate the window switch on the driver's door panel, pull the switch to the top position and hold for 5 seconds until you hear a beep to activate it. Then test the key: press the lock button to raise the windows, and press the unlock button to lower them. This feature saves time and effort, preventing you from forgetting to close the windows and getting caught in the rain or letting dust in. I'm used to checking if it's activated before getting in the car to ensure smooth operation. Technical note: Some models require specific steps before turning off the engine, but the 2021 model is basically the same. Safety reminder: Make sure the windows are clean and free of debris when operating to prevent pinching injuries. You'll get used to it after trying a few times—the key is not to panic. If you make a mistake, just start over; it won't affect other systems.

The method to activate one-touch window lift for the 2021 Excelle key: I tried sitting in the car with the door closed and starting the engine. Then directly operate the window switch: pull it up to the top position and hold for a few seconds until you hear a beep to activate. After completion, test with the key by pressing the lock button to successfully lift the window. The advantage is the convenience of quickly closing the window when exiting the car. It is recommended to ensure the car is stationary before operation to avoid accidents.

Here are the steps to activate the one-touch window lift for the 2021 Buick Excelle: First, get in the car and close the door—it's best to start the engine. Then, pull the driver's side window switch up to the highest point and hold for 5 seconds until you hear a beep, indicating activation. Afterward, test with the key: press and hold the lock button to automatically raise the windows, and press the unlock button to lower them. This method is practical for preventing the interior from getting wet on rainy days. Safety is important: keep children away from the windows during operation to avoid pinching. After activation, test the function and maintain the window tracks regularly. It's simple, quick, and suitable for daily use.
