Went to change the blower resistor pack and when I removed the shroud under the glove box. a blue tube that may be a vacuum tube is hanging down not connected. Does anyone know what it is or should connected to? The dampers seem to be working. By the way a great site to show how to change blower motor and resistor pack on this site.
