C. The in vehicletemp sensor is located in the aspirator which is located in the dash. The aspirator tube is connected to a heater-A/C duct. The air flowing in the duct past the tube creates a vacuum drawing in vehicle air past the sensor. If there is an obstruction in the aspirator tube or the tube is disconnected from the duct air will not be drawn past the sensor and it will not be able to accurately measure the temp inside the vehicle.

The inside of an EATC equipped vehicle never feels as cool as the temp setting. The AC system checks out OK including the sensors. Tech A says there could be an obstruction in the aspirator tube. Tech B says the aspirator tube could be disconnected from the duct. Who is right?
