What are the reasons why car window glass cannot be raised or lowered?
1 Answers
The reasons why car window glass cannot be raised or lowered are: 1. The window control function is turned off: Cars are equipped with a function to independently control the windows of the passenger seat and the two rear doors. Pressing this function switch will disable the window control; 2. There are foreign objects in the window guide channel: Higher-end models are equipped with an anti-pinch function for the windows. Foreign objects in the guide channel, aging of the guide channel rubber, or excessive dust accumulation can trigger the anti-pinch function, preventing the window from being raised; 3. The window motor is overheated: The raising and lowering of the window glass are controlled by the window motor. Frequent operation of the window can cause the motor to overheat, entering an overheat protection mode. At this time, the window control function will temporarily fail until the motor cools down and returns to normal; 4. Faulty control switch: Older cars with frequent window operation may experience control switch failure. Initially, it may require pressing hard to get a response, and later it may fail completely; 5. Wiring fault: Self-modified wiring or the addition of a one-touch window function may cause a fault in the window control circuit, rendering the window regulator ineffective.
