How does the computer control the car chassis?
The technology that controls the chassis has made major strides since the birth of the car. In particular, computer technology has greatly improved safety and reliability by electronically controlling the chassis, allowing the adoption of features such as Electronic Stability Control.
How does an electric window winding system work?
An electric window circuit A typical system is similar in many respects to a manual window-winding mechanism, except that the manual winder handle is replaced by a motor. The system usually consists of a two-way control switch in the dashboard or centre console, wired via two circuits to a motor in each door.
Where does the power come from for an electric window?
Generally the power for the window circuits (which draw a large current) is supplied direct from the battery through a relay (or relays) actuated by turning the ignition on. Find the relay position from your car handbook.
What are the symptoms of a bad power window switch?
If you suspect your power window switch is going bad or failing, watch for the following symptoms: 1. All the windows quit working If all of the windows quit working at once, meaning there is no response when you push the power window switch, chances are there is a loss of power in the electrical system.
How does the power switch on a window work?
When the driver presses one of the switches, one of the two side contacts is disconnected from the ground and connected to the center power contact, while the other one remains grounded. This provides power to the window motor. If the switch is pressed the other way, then power runs through the motor in the opposite direction.

How are the four windows on a car controlled?
We’ll go through the wiring on a basic system — one that allows the driver to control all four windows on the car and can lockout the controls on the other three individual windows. On this system, the power is fed to the driver’s door through a 20-amp circuit breaker.
How are power windows connected to the ground?
Two contacts, one on either side of the power contact, are connected to the vehicle ground and to the motor. The power also runs through the lockout switch to a similar window switch on each of the other doors.
