Does pressing the window switch a few times when the window is frozen cause damage to the car?

Pressing the window switch a few times when the window is frozen generally does not cause damage to the car. Even if there is an issue, in most cases, it would only result in the window motor or fuse being damaged, which can be replaced. When the car window is frozen, it is not recommended to force the window up or down. Most modern vehicles are equipped with an anti-pinch function for the windows, which can also serve to protect the window. Frequently forcing the window up or down when it is frozen can easily lead to damage to the window fuse or motor, so it is best to avoid opening the window when it is frozen. Methods to deal with frozen car windows: The most common method is for the car owner to start the car first, wait for the temperature to rise, then turn on the warm air conditioning inside the car, directing the airflow toward the front windshield, and wait for the ice to melt before wiping it clean with a dry towel. For ice on the rear window, the car owner should not immediately use the windshield wiper or a hard card to scrape it off, as this could damage the wiper motor or scratch the window glass. Instead, use a hot towel to melt the ice, then wipe it clean with a dry cloth. Avoid spraying hot water. Alternatively, the car owner can use some professional de-icing sprays to melt the ice on the rear window, which will not leave scratches on the rear window glass.
A few days ago, my car was parked outside, and in the morning I found the windows frozen. I pressed the window switch several times with no response. Later at the repair shop, I learned this action can actually harm the car, especially the window motor. The motor has to overcome the resistance from the ice, increasing the load and making it prone to overheating and burning out—replacing it isn’t cheap. Worse, the glass edges and sealing strips can also deform or even crack under stress, making repairs even more troublesome. It’s advised not to risk pressing the switch forcefully. Instead, use warm water poured slowly along the edges or a dedicated de-icer. Also, try to wipe the windows dry before parking to avoid moisture freezing. These small habits can help protect the window system for longer durability.
In winter, I've done many silly things when the car windows froze, including repeatedly pressing the window buttons. Now I understand it causes significant harm to the car. The main issue lies in the electronic control system—each button press makes the motor attempt to start, but the ice jams the glass, causing a surge in load. This triggers the motor's overheating protection, but repeated operations can fatigue and fail the protection device. Moreover, the window tracks being stuck by ice may damage the slider mechanism if forced. If the glass is frozen too tightly, pressing hard might even crack the glass edges. The solution is simple: start the car, turn on the heater for a few minutes, or apply some alcohol on the seals. Protecting the windows not only saves money but also ensures you won't face trouble closing them on rainy days.
