No, initially I was driving down the interstate and turned the heater onto the floor. In practically no time, the windows fogged up. Turned the setting from floor to defrost, and turned the AC on to help with the moisture. Had to pull over as I totally couldn't see, eventually rolled the windows down, and switched the temperature from hot to cold. Got the windshields cleared, and rolled the windows back up, switched the temperature back over to hot, and the windows started fogging up again. Eventually figured out a combination that would keep the windows clear without me freezing to death. It was: front windows cracked about 1/4 inch, air flow on floor, temperature at about 3/4 from all the way hot. When the car was new, we had it to the dealer twice 'cos we smelled coolant in the cab whenever we turned on the heater, but the techs never found anything wrong. I'm wondering if there is a valve of some sort somewhere in the system, possibly connected to the temperature cable?
