What Are the Reasons Why the Car Window Glass Cannot Be Rolled Down?
1 Answers
The reasons why the car window glass cannot be rolled up or down include: deformation or damage to the glass mud slot; loose screws fixing the window regulator; damage to the window regulator; deviation in the installation position of the guide rail. If the power window cannot be rolled up or down, first check whether the problem occurs with some windows or all windows. The specific reasons why the car window glass cannot be rolled up or down are as follows: 1. Damage to the window regulator motor or poor contact of the electronic control wiring harness: If there is a burnt smell or noise inside the door panel when the window button is pressed for a long time, it is likely that the window regulator motor components are damaged. 2. Motor overheating protection: To protect the power supply circuit, most window regulator motors are equipped with an overheating protection mechanism. If the components overheat for some reason, the motor will enter the overheating protection state, resulting in the window regulator malfunctioning. 3. Excessive resistance in the glass guide slot: The door glass guide slot is a detail that is often overlooked. During use, dust can accumulate in the glass guide slot, increasing resistance, which may over time affect the smooth rolling up of the glass. 4. Loss of computer data: Disconnecting the car battery, disconnecting the power or ground wire of the window control module during maintenance of other systems, or strictly prohibiting starting the engine due to power loss, etc., can all cause the initialization data of the window to be lost, resulting in the window not being able to roll up or down.
