Aspirator: Description and Operation
Motorized In-Car Aspirator
The Motorized In-car Aspirator (MIA) detects the air temperature within the passenger compartment when air-conditioning is selected. A small motor
driven fan (blown aspirator) draws air across the thermistor, which changes its electrical resistances in response to changes in air temperature, converting
a temperature rating into an electrical signal.
