What Causes the Failure of Car Power Window Switches?
1 Answers
Car power window switch failures can be attributed to the following reasons: Power window regulator switch issues: Water entering the switch interior due to cleaning the door panel or opening windows during rainy weather can lead to poor contact on the internal circuit board. Natural wear and tear over time or short circuits can also cause the switch to malfunction. Power window regulator problems: The regulator motor is a small DC motor with internal carbon brushes. As usage increases, the carbon brushes wear down and become shorter, eventually reaching a limit where the regulator ceases to function. Water ingress or poor internal contact can also damage the regulator. Additionally, wear and tear on the regulator bracket can cause looseness, obstructing window movement and triggering the anti-pinch sensor.
