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.

Hope this helps

It is one of two things...

Bad heater core and it is leaking coolant into your system as said...

or

You drain line is clogged and you're filling up that way.. how big of a puddle do you have under the truck from the ac when you stop?

the puddle is 'ice' moisture in the evaporator case-- normal and the size of the puddle will depend on the relative humidity-----


here in the desert== no puddle

So if i understand right all i have to do is run my truck on recirculating and the puddle under the truck is normal?
Yes, down here in the south I get a large puddle under the truck at each stop.
