Alright guys, here's my situation... let me know if anyone else has run into this problem. I live in Massachusetts, that last few weeks there has been a couple of extremely hot humid days... when I let the vents run, whether it warm or cold (there is no issue when the A/C is on though), there is a ton of moisture that gets into the cabin. It gets so bad, I can see and feel condensation on the vent grills and on the back of the blinker rod. There's also been several times where there has been so much condensation on the inside, the windows have fogged up to the point I can't see out any of them.

Has anyone had similar problems? And does anyone have any ideas on how I can fix this because I obviously don't like driving with the A/C on the whole time.
