Smoke from A/C vents.



I have a 2003 dodge neon se, my daughter was driving my car and noticed smoke coming from the vents when the a/c is on. A friend of hers was nice enough to put anti freeze since it was low ( I thought when you get an oil change that also includes topping off the radiator flud?) What exactly does that mean? There is no smell but now I have to put it in the shop.



Smoke can mean many things. Was there a sweet coolant smell coming out of the vents? Its possible the low coolant and the smoke are related to a blown heater core. The heater core is basically a radiator, where the hot engine coolant runs through to heat the interior of the car. There is a fan which blows over the heater core and heats the interior air. While she had the A/C on, the heater core could still be bad and leaking coolant, causing the smoke.

If there was no sweet smell, it was more than likely the A/C working so well that it was causing an icy fog which does happen from time to time, depending on the humidity levels outside.

I would keep track of the coolant level, see if you lose anymore and if so, get the heater core checked out.
