What are the reasons why the electric car window glass cannot be raised?

Reasons why the electric car window glass cannot be raised include damage to the window lift motor or poor contact in the electrical control wiring harness. Specific reasons: If there is a burnt smell or abnormal noise inside the door panel when holding down the window button for a long time, it may indicate that the window lift motor components are damaged. In this case, it is recommended to directly visit a 4S shop or auto repair shop to replace the window lift motor. To protect the power supply circuit, most window lift motors are equipped with an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window lift to malfunction. The door glass guide channel is an easily overlooked detail. During use, dust can accumulate in the glass guide channel, increasing resistance, which over time may make it difficult to raise the glass. Temporary solution: Turn on the ignition switch, pull and hold the switch to raise the glass. After the glass reaches the top, continue to hold the switch for more than 3 seconds. Release the switch and immediately press and hold it again to lower the glass to the bottom and wait for more than 3 seconds. Repeat the raising action once more to complete the initialization procedure, and the window lift function will be restored.
Last time my car window also got stuck, the mechanic told me there are several common causes. Poor contact in the switch button is a high-frequency issue—if the window doesn’t respond or reacts sluggishly when you press the button, it’s likely the culprit. Another possibility is a faulty lift motor; a burned-out motor or worn gears can cause the glass to get stuck halfway. Poor wiring contact shouldn’t be overlooked either, especially if wires inside the door panel are pinched, leading to short circuits. Another easily overlooked issue is dust buildup in the tracks or aging/deformed rubber seals, which can jam the glass mid-movement. The most troublesome is a control system malfunction, which requires specialized computer diagnostics. I’d suggest first checking the fuse yourself, and if that doesn’t work, seek professional repair ASAP—after all, getting caught in the rain with a window that won’t close is a nightmare.
As a car owner who has personally modified car windows, I've encountered this issue multiple times. The causes are generally concentrated in weak or stuck motors. As the motor ages, its driving force becomes insufficient, causing the window to stop halfway. Wiring issues are also common, as the internal wiring in the door panel can loosen or break after years of vibration. Wear on the small contacts inside the switch button can prevent signals from being transmitted, especially noticeable in winter. Lack of lubrication or deformation in the guide rails can also cause problems, as can aging rubber strips gripping the glass. If there's a clicking sound during operation, it's likely due to loose or misaligned cables. It's recommended to clean the guide rail grooves quarterly and apply specialized lubricant to effectively prevent malfunctions.
