Windshield fogging inside on a 1996 Dodge Caravan



My daughter has a 1996 Dodge Caravan. When it is cold out and she turns the heater or defroster on the windshield fogs up on the inside. I told her I think it's is caused by a leak in the heater core. Anyone else with any other ideas? Thanks


Response:
This depends on IF the van has an operational Air Conditioning System. This "Fog" is caused from Air Density changes. When you first start it up and turn on the Defroster(hence the name) it also turns on the A/C Compressor. Pop the hood and watch the compressor clutch. Especially these past few days. But this SHOULD evaporate within a couple minutes unlike Anti-Freeze.

    I have a 96 Dodge Caravan. The HVAC is only blowing out of the dash vents. I have tried the calibration procedure and it passes (no lights). During the process it blows hot, cold and through all of the vents...dash, floor and defrost, but once it is completed it then goes back to blowing out of the dash only. Also, not sure if it's related, but getting ghost wipes on rear wiper. Any ideas?
