I have a 99 chevy lumina w 3.1 engine 185000 miles
today mist or fog of some sort began blowing out of the windshield defroster vent. It is 70 F here and very humid from the rain. Is that a contributing factor or is it a major repair issue?

When it is very humid out and you have the air on it is normal at times. My 04 chevy truck does it to. I would not worry about it at all...
