Cause of Left Front Window Malfunction in Excelle?
1 Answers
Cause of Left Front Window Malfunction in Excelle is due to poor button contact, failure of the button to reset, causing the lifting device motor to continue running, or high temperature and wear of the carbon brush leading to poor contact. Here are some related extended information: 1. Principle: The car window lifter uses a permanent magnet DC motor to drive a small pulley, which is wound with steel wire. Controlling the forward and reverse rotation of the motor controls the window's lifting and lowering. 2. Damage mechanism: It may be due to occasional button failure, causing the window to reach the top but the motor still not releasing, keeping the steel wire rope under tension. Over time, the steel wire rope becomes frayed and unable to operate.
