Had the heater worked on a couple years ago and when the weather is cold (which it hasn't been the last 2 winters but is this year) the fan blows and smells musty and the windows fog and then freeze. The only places that are clear is in front of the 2 front seats on the windshield.
 
try wiping it with paper towel. if it comes off easy, then it is just condensation. your a/c should clear it. if it smudges and is greasy,then your heater core is spewing out anti-freeze.
 
Maybe your cabin air filter is clogged. it is possible that there is a leak from your heater core but you would smell the anti-freeze.
As a temporary solution crank up the heat and open one rear window slightly. Make sure you are not recirculating air either. turning the defroster or the AC can help also.
