1994 2.4L Galant ES- the inside of my windshield fogs up in the cold wether. Had theAC checked and is fully charged and works in the summer. The heat is working, that is, hot airis being deliverd but not with as muchvolume(as opposed to temperature). Could it be the heater core or is there some kind of condenser/vapor remover within the car that is not functioning? Appreciate your help

 

It's your heatercore.

 

There is nothing wrong... it happens. Pure chemistry

 

Stop smokin them blunts in the car! Problem solved.
j/k
Its probably nothing to worry about, if it were your heater core, you would have smelled it by now.

 

You would also have a puddle of coolant the pass side floor.

 

my '06 did that.
they replaced the heater controls.
