My 99 Durango has started 'fogging' from the interior vents. When the A/C is
on, it blows a THICK fog out of all vents. It is so thick you have to open
the windows to see. If I move the temp control to warmer, it immediately
stops fogging. I am leaning towards either a plugged drain ( I can't find
the drain ), or a leaking heater core. The fog has a pronounced oily feel
and a slight anti-freeze odor. Any ideas? Thanks in advance for any info.
I've had 'em go bad enough to make the windows totally fogged, everything
greasy, and for some weird reason there was very little antifreeze
smell...much less than when I've just had a leaked that dripped down and
soaked the carpets. No clue as to why the difference, unless that quantitiy
of airborn antifreeze burns out your ability to smell it right away.
