Abstract
A control for a resistive heating element embedded within a motor vehicle seat. A transistor is biased into conduction to energize the heating element when the temperature of the element is below a threshold that is adjusted by the vehicle operator. A fault sensing system monitors operations of the control and de-energizes the heating element if a fault is sensed.
