OPERATION
Turn on the ignition switch, and the transistor Tr will be turned on by the timer circuit. This will turn
l
on the power window relay allowing the power window to be opened and closed.
Turn the ignition switch from on to off, and the timer circuit will be activated to keep transistor Tr
l
on for 30 seconds allowing the power window to be opened and closed.
Moreover, if the front door is opened, the timer circuit will stop to turn off the transistor Tr. This
will prevent the window from being opened and closed.
