Bob Schmitt posted the answer to this years ago, check the IML archives. In addition to Bob's easy Velcro fix, I found that you can ream out the 3/32 holes which retain the rowel pins to 0.125 and use 1/8 inch rowel pins instead; this is a more or less permanent cure. The fogging sounds as is you may also have a bad heater core - check under your carpet for signs of leakage before serious damage is done to your car. If you have to add coolant, it's a good bet some of it is going out the heater core. The AC should be dehumidifying the air so that there isn't any condensation inside the car. You can add some warm air by moving the temp control so that you don't freeze yourself out, but running the AC should clear the windows almost immediately of inside condensation, and if it doesn't, suspect a heater core leak.
