The mode switch is the one that selects the type of ventilation you want - defrost, heat, vent, A/C, etc. It is a two part device - and electrical part to control the fan, A/C clutch, etc. and a vacuum part that controls the ventilation flaps in the plenum. The vacuum part is shipped with a small amount of grease sealing the vacuum control. Over time, this grease evaporates/ solidifies/whatever and no longer provides a good seal. This leads to erratic ventilation systems. The switch can be rebuilt at home (see 'zine #3) or replaced with a new unit.
