Where does the power from the window circuit come from?
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. Use a test lamp to check that current is reaching the relay.
Which is the most common fault with electric windows?
The most obvious fault with electric windows is that they fail to operate. If the problem occurs on all windows you can be pretty sure that the fault is in the main wiring circuit , and this is also the region to check first even if the problem is restricted to just one window.
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.
How can I check the current on my electric window?
Check for current on both motor terminals. To continue checking remove the door trim so you can get at the motor. Generally you can do this by unscrewing items such as ashtrays, door handles and control panels and then unclipping the trim panel.
Where does the power come from in a power window?
Automotive power windows derive power from the battery electrical system. Typically, battery voltage is routed to the fuse panel where a fuse, relay, or circuit breaker is used to transfer voltage to the power window master switch (or control module). The master switch is usually located in the driver door or the console.
What kind of regulator does a power window use?
Automakers use three basic types of window regulators in their power window systems. In all these systems, an electric motor with a sprocket provides the momentum. The difference is in how the regulator functions after the gears mesh.
