What are the reasons for the failure of the window lift in the Ford Escort's driver's compartment?

[LeLola]

Here are the specific reasons for the failure of the window lift in the Ford Escort's driver's compartment: 1. Damage to the window lift motor or poor contact in the electrical control wiring harness: If there is a burnt smell or abnormal noise inside the door panel when the window button is pressed for a long time, it is likely that the window lift motor component is damaged, and in this case, the glass lift motor needs to be replaced. 2. Motor overheating protection: To protect the power supply circuit, window lift motors generally have an overheating protection mechanism. If the components overheat, the motor will enter an overheating protection state, resulting in the failure of the window lift. 3. Excessive resistance in the glass guide channel: During use, dust can accumulate in the glass guide channel of the door, increasing resistance, which over time may make it difficult for the glass to rise.
