1. An improved system for automatically activating power-operated window and roof panel motors and motor actuators in a motor vehicle so equipped, the system is comprised of:

  • a vehicle battery with a positive pole and a negative pole wherein said negative pole is connected to a vehicle ground,two groups of relays, each relay of said two groups has a set of normally open contacts, each said set of contacts is in a separate circuit between said vehicle battery and a single motor or motor actuator to operate said single motor or motor actuator in one direction,two controlling circuits for operating said two groups of relays,a first circuit that controls the operation of a first group of relays, said first circuit is comprised of;

    a first switch that is closed by closing an ignition switch of the vehicle, said first switch is normally open and tied to said positive pole of the vehicle battery, said ignition switch is also tied to said positive pole of the vehicle battery,a first transistor arrangement to operate said first group of relays, said first transistor arrangement is comprised of;

    said first switch,a first timer that activates a first transistor,a second timer that activates a second transistor, said first timer and said second timer both are activated by closing said first switch, said first transistor is disabled by closing said first switch, said first transistor is enabled by opening said first switch and also by activating a first prime transistor, said first prime transistor has a base tied to said positive pole of the vehicle battery and said first prime transistor also has a collector tied to an emitter of said first transistor, said second transistor has a base tied to said first switch, said second transistor also has a collector tied to said base of the first prime transistor, activating said second transistor disables said first prime transistor, all of the coils of said first group of relays are in parallel with each other and tied together at an end of each of said coils, an other end of each of said coils of said first group of relays is tied to the positive pole of the vehicle battery, said first transistor has a collector tied to said end of each of said coils of said first group of relays, opening said first switch after said closing said first switch activates said first transistor, activating said first transistor engages said first group of relays, engaging said first group of relays energizes said motors or motor actuators in a first direction,a second circuit that controls a second group of relays, said second circuit is comprised of;

    a second switch that is not closed by closing said ignition switch of the vehicle, said second switch is normally open and tied to said positive pole of the vehicle battery,a second transistor arrangement to operate said second group of relays, said second transistor arrangement is comprised of;

    said second switch,a third timer that activates a third transistor,a fourth timer that activates a fourth transistor,said third timer and said fourth timer both are activated by closing said second switch, said third transistor is enabled by a second prime transistor, said second prime transistor has a base tied to said positive pole of the vehicle battery, said second prime transistor also has a collector tied to an emitter of said third transistor, said fourth transistor has a collector tied to said base of said second prime transistor, activating said fourth transistor disables said second prime transistor, all of the coils of said second group of relays are in parallel with each other and tied together at an end of each coil, an other end of each of said coils of said second group of relays is tied to said positive pole of the vehicle battery, said third transistor has a collector tied to said end of each of said coils of said second group of relays, opening said second switch after closing said second switch activates said third transistor, activating said third transistor engages said second group of relays, engaging said second group of relays energizes said motors or motor actuators in a second direction,closing said first switch disables closing said second switch.
