What is the function of power windows?

[DiGriffin]

Power windows refer to windows that automatically raise and lower the glass using power. They are operated by the driver or passengers through a switch that activates the window lift motor circuit. The motor generates power, which is transmitted through a series of mechanical transmissions to raise or lower the window glass as needed. More details are as follows: 1. The power window system mainly consists of a lift control switch, motor, lift mechanism, and relay. The motor is typically a bidirectional permanent magnet motor, which rotates forward or backward by controlling the current direction to achieve window movement. 2. There is a window lock switch on the window; once turned off, the power window switch will no longer function. 3. Power windows also include a thermal switch, which primarily controls the current to provide protection and prevent motor overload. Additionally, if the window glass cannot move freely due to other reasons, the thermal switch will automatically cut off the circuit. 4. There is also a safety feature where some rear windows cannot be fully lowered to the bottom to prevent children from sticking their heads or hands out of the window, thereby avoiding potential traffic accidents.

When we first bought our new car, I was particularly fascinated by exploring all its features. The most practical aspect of the power windows is the one-touch up and down function, especially useful when the weather suddenly turns rainy and you need to close the windows quickly. In my old car, I had to manually crank the windows, but now, from the driver's seat, I can control all four windows with just a button press. The rear windows even have child locks to prevent kids from playing with them. What gives me the most peace of mind is the anti-pinch feature, which automatically retracts if it detects an obstacle. Once, my dog jumped at the window and triggered this safety mechanism. I genuinely appreciate these thoughtful design details—they make opening and closing the windows during my daily commute so effortless.

After repairing cars for over a decade, I've noticed that car owners often overlook the anti-pinch function of power windows. When you hold the switch to close the window, the resistance sensor immediately reverses the motor to lower the window upon detecting any obstruction – this safety feature is more sensitive than most people realize. The control panel on the driver's seat is particularly crucial as it can lock other windows, an essential function for families with children. Also worth mentioning: accumulated dust in window tracks can cause noisy operation during raising/lowering. Regularly spraying some window lubricant can extend the motor's lifespan.

During the last test drive, I found the electric window controls to be much smarter than expected. A single press of the button lowers the window all the way down automatically, while a light tap opens just a crack. When friends in the back seat couldn't reach the switches, I could easily operate the windows for them from the driver's seat. I often forget to close the windows when it rains, but now pressing the lock button on the key for five seconds automatically rolls them up—this feature has saved me three times already.
