Ice forming on the INSIDE of my front windshield on 2006 Hyundai Tucson

I recently had my car's transmission replaced in Oct 2012 and now that winter has arrived, I'm experiencing a problem I didn't have last winter: Ice on the inside of my front windshield. Is it possible the dealer jarred some seal lose or somehow broke my heater core?

not heater core unless its leaking but could be issues under the dash. have heater and a/c control module scanned for codes and post
Thank you. I will do that. This is extremely frustrating.
possible excessive humidity in your vehicle.
Today we reached a balmy 49 degrees so I checked & noticed the back carpet was moist from the washer fluid jug even though it was not leaking. I removed that so we will see. I'm trying everything. Thank you.
