it was really muggy out the other day, so instead of taking my t-tops off, i used my a/c which i seldom you. while driving and having it on for a good while on norm and fan high, i noticed a little bit of like white smoke comming out of the vent above the radio so i just turned it off, and turned it back on and it was gone. there was no odor or heat, just real cold. it did it a few days later too. what could have it been?

 

Might've just been condensation.. You know how when it's really cold outside and you exhale you can see the smoke? Probably something similar.
