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.
