Car Window Won't Roll Up or Down?
1 Answers
Besides the possibility of the window lock switch on the driver's side master control panel being activated, another reason could be that the window lift motor has been operated repeatedly in a short period, causing it to overheat. When the heat cannot dissipate quickly enough, the power window may enter an overheat protection state. Generally, performing continuous window up-and-down operations dozens of times will trigger thermal protection. If the window guide channel is dirty or the glass surface has increased friction, thermal protection may occur earlier. Here is relevant information: 1. Window lift motor damage or poor electrical harness contact: If you notice a burnt smell or unusual noises inside the door panel when holding down the window button, it is likely that the window lift motor components are damaged. 2. Motor overheat protection: To protect the power supply circuit, most window lift motors are equipped with an overheat protection mechanism. If components overheat for any reason, the motor will enter an overheat protection state, causing the window to stop functioning. 3. Excessive resistance in the glass guide channel: The door glass guide channel is often overlooked. Over time, dust can accumulate in the guide channel, increasing resistance and potentially making it difficult for the glass to rise smoothly.
