A heating/cooling question. The windows fog up, down low by the defrosters, no matter if he washes them. There's no smell. The fog is probably just water vapor that's stuck in the heating box. It's condensing on the cool glass. The evaporator drain is probably plugged, causing the water to collect. Could also be the heater core, leaking a small amount of antifreeze.
