Normal Operation and Fault Conditions

The window control switch(es) sends 2 separate signals to the window motor: up and down. When the window control switch is pressed to the first detent position, a 12-volt signal is sent to the window motor to request an up or down operation. When auto up or auto down is requested (switch pressed to the second detent position), the window control switch provides a 12-volt signal on both the up and down line simultaneously. During an auto up or auto down request, the window motor determines intended window direction by the signal first received. If the window control switch is pressed too quickly to the second detent position (less than 5 ms of time between first detent signal and second detent signal), the window motor is unable to determine the intended direction request and will not operate until the window control switch is released and pressed again. The up and down feeds to the window motor are all low current. The high current required to operate the front window is supplied through a dedicated power and ground circuit to the motor.
