Water in heater??
 

First let me say Hi All! it's been a long time since I
visited!

My friend has a '97 Wrangler Sahara (I forget which _J).
Today turned cold and rainy, he said he had so much steam
inside the windshield he couldn't hardly drive to work. I
vaguely remember conversations here about leaves clogging up
the cowl vent drain and water getting into the heater unit.
Could someone point me in the right direction for fixing
that?

Thanks!
