Re: heating and a/c system please help
It's the small black item at the end of a covered wire clipped to the front of the hood latch/radiator support. Single plug with safety catch. New unit is about $14 at www.rockauto.com. BTW, it's a thermistor; a resistor which changes value as temperature varies.
