1996 Ford Explorer, Heater fan noise

Sounds like something is stuck in my heater fan, anyone have directions with pictures on how to remove to get access to the fan? I just looked under there and i didn't see that many bolts.
Thanks

nevermind sorry, i asked one of my coworkers at work who used to work for a junk yard and he showed me. i found a piece of sand paper in my heater fan. No idea how it got there.
