My 2008 Outback is blowing a very light/fine smoke through the vents! It just started today. It has no odor and it would alternate through the front vents. Has anyone experience this or has any advice? I just had an oil change recently and the air filter was clean...help!!!

Did you have the A/C on ? My car has done this several times with the a/c on....its steam because it dissapates quickly.

Can you smell the smoke?

Does is dissapate quickly ?

is the weather oddly humid too?

might just be some condensation if there's no smell and everything is working well.

might be a good idea to investigate changing the cabin air filter and confirming the A/C drain is clear.

It's almost certainly water vapor. Ever opened a freezer on a warm day and seen the "fog" rolling out? Same thing.

On a positive note, that means your A/C is working pretty well. ;)

it is probably just condensation, or i call it frost. i can sometimes make mine do it by running the ac for a while and then turning the blower off. when i turn the blower back on it will put out smoke like stuff.

the AC system is sealed, just like the engine cooling system that provides heat. the AC sends cold refrigerant through a ''radiator'' type thing and the blower then moves the air around it , cooling it is goes.

so if the AC is creating cold air, the system is still sealed and working. anything else is environmental.
