What is the reason why the window can be lowered with one click but not raised with one click?

Reasons why the door glass cannot be raised: 1. The window lift motor is damaged or the electrical control wiring has poor contact: If there is a burnt smell or abnormal noise inside the door panel when the window button is pressed for a long time, it is likely that the window lift motor component is damaged. In this case, it is recommended to directly contact a 4S shop or auto repair shop to replace the window lift motor. 2. Motor overheating protection: To protect the power supply circuit, most window lift motors are equipped with an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window lift to malfunction. 3. Excessive resistance in the glass guide channel: The door glass guide channel is an easily overlooked detail. During use, dust can accumulate in the glass guide channel, increasing resistance, which over time may make it difficult to raise the glass.
I once encountered an issue where the car window could roll down with one touch but not roll up, which was quite annoying. In my car, it's usually a problem with the window switch, like poor contact in the up button or dust blockage. If it only goes down but not up, you can try this method: turn off the car's power for a few minutes and then restart it. Sometimes the electronic control system resets and returns to normal. Additionally, check if there are any physical obstructions in the door's lifting mechanism, like small stones stuck in the track or slow response due to motor aging. I remember last time I spent a few dozen bucks to buy a new switch and replaced it myself, which solved the problem—it's not a big deal. However, if it happens frequently, it's better to visit a professional shop to check if there's a short circuit in the wiring to avoid more serious issues later. In short, this kind of problem is quite common, and most of the time, it can be fixed with simple repairs.
From my experience, this issue often stems from the control module or the anti-pinch function. For example, if there's no response when you press the one-touch button, it might be because the system detected excessive resistance and triggered the protection mechanism, or sometimes it's due to incorrect sensor calibration. Loose wiring connections can also cause this—I recommend opening the door panel to check if the wires and plugs are intact. Another common cause is low battery voltage affecting the control system—if the voltage is unstable, malfunctions are more likely to occur. I've dealt with this a few times myself: first, use a multimeter to check the voltage, then inspect the fuse box for any blown fuses. If you can't fix it yourself, just take it to a repair shop to update the software module—it costs a few hundred bucks but is very reliable. Don't delay fixing this issue, or you might end up with a window that won't close during the rainy season, which would be a real hassle.
