Whenever i have my a/c on for say more than ten minutes it spits out a noticeable white fog. Ive goggled it and most people say its just condensation but wanted to check and see what you guys thought it smells kinda funny and is extremely cold.
Make sure you are not losing coolant. If there is a slimy residue on the inside of the windshield that could also indicate a leaking heater core. If it is coolant from the heater core you don't want to be breathing that too much.
That Said, The most comon cause of "fog" from the A/C vents is operating the A/C with the vents set on fresh air intake. The A/C works best when set to recirculate because it dehumidifies all the air in the cabin.
