Car door lifting switch failure, glass automatic lifting
Car door lift switch failure and glass automatic lifting problems are usually caused by several common reasons, including switch failure, motor damage, rail blockage and so on. Solutions to these problems include replacing switches, checking fuses, motor cooling, rail cleaning and lubrication. The details are as follows:
Switch failure: If the switch is damaged or fails to function, a new switch may need to be replaced.
Motor problems: The motor may stop working due to overheat protection or need to be replaced due to internal damage. In this case, waiting for the motor to cool or replacing it with a new motor may be a necessary solution step.
Guide rail and rubber strip problems: Blocked guide rail or aging of rubber strip will affect the lifting of glass. Cleaning the rail and applying lubricating oil, or replacing aging seals can solve these problems.

Why is the door light always on?
1. If the door is locked and the light is constantly on, it is likely that there is a problem with one of the switches on the door. At this time, you can try to manually open a door and press the switch one by one, and determine which switch is abnormal by feeling. Usually, the reasons for switch failure are mostly related to poor contact caused by partial oxidation of electric shock. The warning light on the door is designed to indicate whether the door has been properly closed.
2. The door warning light is constantly on, which means that at least one door is not closed correctly. Here's how to deal with it: First, check each door one by one to make sure they are properly closed; Secondly, if the door is closed but the warning light is still on, it is necessary to check the door sensor switch one by one, and replace it in time once a failed switch is found.
3. If the warning light on the door continues to light, it usually means that the door is not closed correctly. To solve this problem, first make sure that each car door has been carefully closed; Then, check whether the door induction switch is faulty, once the fault switch is found, it should be replaced in time. In addition, the car battery indicator is used to show the working status of the battery, which is also an indicator that needs attention.
4. When the door light is on, it usually means that at least one door has not fully closed. Once this light is observed, immediately check that all doors and front covers are tightly closed and ensure that all doors are properly closed before driving.
