Yeah the infection is beginning! Must be something in the air lol. I currently have the same problem but my fan is not seized it just spins when it wants to. If you turn your a/c on and your fan is not spinning then yes your fan seems to be the culprit. Until mine goes all fully I am not going to replace it just yet. I'd say mine works about 80% of the time just randomly will not spin. I'll fix it sometime soon. Everyone else get some respirators for your fans before you get infected too!
