What is the reason for the window not responding to up and down movement with only the motor sound?

[DeDaisy]

Detailed explanation and solutions for the reason why the window does not respond to up and down movement with only the motor sound are as follows: 1. Damaged window regulator motor: If you press the window regulator switch and can hear the sound of the window regulator motor working, or the lifting speed is slow, or sometimes it can move up and down and sometimes it cannot, there is a high possibility that the window regulator motor is damaged. Solution: Replace the window regulator motor. 2. Motor overheating protection: Most window regulator motors have an overheating protection mechanism. If the components overheat due to some reason, the motor will enter the overheating protection state, which will affect the window's up and down movement. Solution: Wait for the window regulator motor to cool down.
