A central air conditioner unit fan is blowing but no cold air is coming out of vents?

This is a partial answer. If the fan is blowing and air is coming out of the vent, but it's not cold, then I'm not sure what you can do.
But, if the fan is blowing but no air of any temperature is coming out, then perhaps the evaporator coil has frozen. This can happen especially if the thermostat has been set for a temperature much cooler than the outside temperature. One way to check for this is to look to see if there is ice on the insulated copper line coming from the AC unit outside.
To fix this problem, simply turn off the AC for a few hours. Turn your blower fan on using the manual override switch at the thermostat. This will help melt the ice on the evaporator coil. After several hours, check to see if you are getting air from the vents. Once you are, turn the AC back on--just not so low this time. (Or is it not so high?--Set the temperature in the range recommended by the manufacturer.)
