I have a 2002 Windstar Sport, 3.8L dual heat and A/C. On a recent trip through the Rogers Pass in a heavy rain/snow mix coming down, the only way we could keep the inside of the thing from fogging up was to crank the heat to hi and open both front windows an inch or so. Once the rain slowed down it cleared up with the windows shut. My question is, where and how can I check the drain on the evaporator case. I remember this was a problem on some of the cars I worked on in years gone by. I can't do it anymore so if anyone has some info I can get a buddy of mine to have a look.
