What are the reasons for the failure of the co-pilot window lift?

[TravisFitz]

The reasons for the failure of the co-pilot window lift: line failure; deformation or damage of the glass mud slot; loose screws of the lifter; damage to the window lifter; deviation of the installation position of the guide rail. Recovery method: You can try to disconnect the power supply and reconnect to see if it recovers. In addition, you can also repair the circuit; clean or replace the glass; replace the lifter. Notes: To prevent rainwater from flowing in, there is a rubber band on the inner window frame. After the glass is soiled, the friction with the rubber band increases, and the switch will also be affected, so the glass needs to be kept clean frequently. Small cards are often inserted into the window gap. If not handled properly, the card may fall into the door along the window. The internal structure of the door is complex, and the card falling into the door will cause a series of chain reactions. For example, the lifter is damaged, the door fails, the drain is blocked, etc.
