Abstract
An electrical circuit for lowering windows or shields a predetermined distance, such as for allowing hot air to escape from a parked vehicle. The circuit includes a primary switch to activate motors for lowering windows, and further includes a sensor for stopping the motor when the window is lowered the predetermined distance. The primary switch may activate the simultaneous lowering of a plurality of windows the predetermined distance. The circuit optionally includes a thermostat for automatic operation when a preset temperature is sensed. In alternative embodiments, the predetermined distance and the preset temperature are adjustable.

An electrical circuit for lowering a vehicle window a predetermined distance to allow hot gases to escape from a vehicle comprising:
- a window operably mounted in a vehicle, said window having a raised closed position, a lowered open position and a preselected lowered venting position;
- a motor coupled to said window and adapted to raise and lower said window;
- a power source;
- a primary switch electrically coupled to said power source and said motor for activating said motor to lower said window;
- and
- a sensor adapted to sense when said window is lowered a predetermined distance to said venting position, said sensor electrically coupled to said motor to shut off said motor when said window is lowered said predetermined distance.
