I have a 98 Monte Carlo and after idling, I've noticed what looks like mist coming out of the right two vents. It has no odor and my temperature gauge is fine. My fluids are also fine. There is also a noise which sounds like boiling when I turn the car to the right. It is running fine and only seems to start this after I sit idling for a while.

Is AC being operated at the time you see mist?

It emits the mist with the a/c or only the vent on.

It only does this for about one minute and then it stops and may or may not do it again during the drive.

If humid ait coming into car then mist will happen as it goes across Evaporator. Try this run AC in recirculation mode mist should go away
