Sounds like a leaky heater core. Only real way for coolant to let off into the air passed through the vents.

I just had the same problem.Didn't seem to be leaking anywhere but when I took off the lower hush panel...green fluid everywhere.Change it before it turns into a gusher all over your carpeting.Just a matter of time before it happens.

Same exact problem. No leaks on the carpet, just a pinhole leak in the heater core. I wasn't sure because the last one in another car burst like a dam. I got a nice surprise last night when I dropped the kick panel.
