1998 Saturn Station Wagon Air Conditioning Vent Clog and Fa

Noises problem
1998 Saturn Station Wagon

A few months ago my car, the one mentioned above, began to have problems with its ventilation system. First, there are 4 vents on the dashboard of my car, one on either end and two together in the middle (one made to directed toward the passenger's side and one for the driver). The drivers side has clogged and only gives out a small amount of air, however, all the others work without a problem. And also, at the same time as this, an odd clicking noise began to occur whenever I turn on the ventilation, regardless of whether it is set on A/C or heating at any setting. This leads me to believe it is a problem with the fan(s).

Any help or suggestions are greatly appreciated.
