Hi,
I have a 1999 Dodge Durango 5.2 V8 that started yesterday producing evaporation "fog" out of the vents when you step on the gas. This morning it was running humid. I live in Idaho and there is no humidity. It is currently 60 degrees. There are no leaks, the coolant is full, I do have a faint coolant smell at times. I have taken apart the dash as far as I want to go before going any further. It is acting like there maybe moisture somewhere, but everywhere I have checked it is dry. ANY advice would be great.
Thanks

 

Oh ya, the floorboards and glove compartment are dry also.

 

It's been VERY humid the last few days up this way so I would blame it on that. You are not used to that amount of humidity up this way.
