Yes. It could be your ac drain. You could remove blower motor, see if you could reach the drain and clean it out. Also, you might be able to reach the drain from underneath, but, I think cleaning it out from the top would be best, that way you could clean out the bottom of housing, also.
Another thought, if you've had rain lately or been through the car wash, maybe the windshield or vehicle body has a leak.
I realize this is an old post. In the future hope you don't have any vehicle issues, but, if you do, keep the site in mind. They are always working to improve the site and it's free to ask a question. They have more moderators now, no question should go unanswered.
