Car Window Switch Repair

Power window switches are known to fail over time for various reasons. The most common failure we see is in the connection area itself. This is where two pieces of metal come together, creating an electrical connection, making a ‘click’. That click is the electrical actuation connecting the electricity from your switch button and the actual power window motor that it is attached to the window regulator mechanism in your door.

To be more technical, when the window is powered up there is a lot of current and power drawn from the motor, which creates a good bit of heat. When you attempt to raise window the way to the top or lower it all the way to the bottom, you’ll find your finger on that switch for an extra millisecond or two. This is just enough time to cause a spike in the current in that very moment, where the motor is still requesting electricity and drawing power. As you release the switch, those connections swing or flip open causing an arc of electricity (similar to a lightening bolt) that jumps from one connection to the other. Because there is oxygen surrounding these connections, eventually a burning effect will seen where a carbon layer will cover the connector, preventing a connection from being made.
