Just noticed this as i was putting the Z away for the winter, i never use the heat but had to this time just cause it was gettin a little cold, anyways when the car is warmed up and the heater is at it's highest setting smoke comes out from the vents, it's not a very dense smoke but you can see it, but then it goes away after 5 minutes... any ideas????

 

Ever breathe warm air out your mouth outside in the winter? It usually make smoke when it hits the cold outside air....

 

MN cold weather FTL... I gotta drive my Z or my mother's Bonneville to school and stuff until I finish painting my Grand Am

Should be done within the next couple days, but dang 30-40 degree weather sucks.

 

smart ***.... no but seriously tho anybody know??

 

 

I am being serious...

 

He answered your question. It isn't smoke, it's vapor. It goes away because your cabin slowly heats up and there's not as much of a tempoerature difference between the heat coming in the vent and the cold cabin.

 

BINGO

 

So what your seeing is condensation, not smoke

does the "smoke" smell?

 

yes the smoke does smell... I know everything there is to know about condensation.... I've lived in MN my whole life that's why i know that's not the case...... hard to describe the smell but i almost smells like burn rubber..

 

My car did this when it was really hot outside and I put the AC on...it was like a steam coming from the vents. It stopped after a minute or so and has never done it since.

 

EDIT: mine didnt smell like smoke tho...if yours does I recommend having it checked out.

 

oh well something to look at come next summer car is put away, i was just wonderin if there was any other known problems like this...
