Unfortunately this is the case. If this does not happen all the time then I would not just replace this door until we have more proof.
When you say you can hear the fan running, I would suggest dropping the glove box out of the way and just drive it around like this so that you can literally put your hand on the housing where the fan is and make sure it is turning. I am wondering if this is air being mistaken for the fan. If the fan is running then you should feel air somewhere.
I attached the process below on how to remove this actuator for your review.
