What causes one power window to stop working?
Only one window stops working If only one window stops working, the problem could be a bad relay, fuse issue, bad motor, or the power window switch has failed. The most common reason for one window to stop working is the switch, so this should be looked at by a professional mechanic to have your power window switch replaced.
What do you need to know about power window switches?
Each power window switch is normally supplied a battery voltage signal (with the ignition switch on). The appropriate switch must be manually depressed for window operation. The master switch may allow the driver to depress a particular button for an extra second so that the window may fully retract with one touch.
What happens when the switch is depressed on a power window?
When the switch is depressed in the opposite direction, the voltage and ground signal to the electric motor are reversed; causing the motor to spin in the opposite direction and the window to move in the opposite direction. Window operation is accomplished using the motor and a regulator assembly, which will be discussed in detail below.
Why is my passenger window not working but the driver window is working?
