Try turning the recirculate mode on and see if you still get the problem, you shouldn't because the outside inlet will be blocked off.
that definately wasnt the issue. the fan was actually blowing the air. you could hear it running, and i could turn it on higher but it wouldnt turn off. i did also press the recirc button with no change. the problem was gone then next time i started the car and hasnt been back since.
