Maybe something is in the blower wheel. I found a dead mouse in a customers blower wheel once.

Sounds like you need to pull it to find the problem

I had the same thing happen to mine several weeks ago. I pulled out the Cabin Air Filter from the cowl area under the hood and found some loose foam. From what I could tell, it was from the recirculation door seal. I tucked what I could back in place and pulled the rest out. Also found that the filter was the wrong one and put the correct one in. Haven't had any problems since.
