What's the reason for the left front window of the Buick Excelle not rolling up?

[SanCollin]

The reasons why the left front window of the Excelle cannot be rolled up are as follows: 1. System issue: There may be some problems with the electronic control system from the factory, and the only solution is to drive back to the 4S store to update the system. 2. Motor overheating protection: To protect the power supply circuit, the window lift motor generally has an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state. If the window lift system fails due to this situation, it will return to normal after waiting for a while. 3. Excessive resistance in the glass guide channel: During use, dust can accumulate in the door glass guide channel, increasing resistance. Over time, this may make it difficult for the glass to rise, and in severe cases, it may trigger the anti-pinch function. Regularly cleaning with water can help protect the guide channel to some extent.
