Help, Fan Rattling behind dash when AC is on.
When my AC/Heat is on, I can hear the fan rattling behind the passenger side Dash. I plan on taking the dash apart today but have never ripped out that much of my dash. I am going to look at the fan, but most likely have no idea what to look for. Dealership mentioned bearings, I supposed I can snag those for cheap and replace them myself if thats it. For the record, the Heat/AC still works, but the noise is getting worse and I dont want something to break and it end up more expensive.
If anyone can tell me what to look at or check or what part might be bad, I would find it tremendously helpful.
Also if anyone has a walkthrough or pictures of how to correctly take my Passenger side Dash apart... it would help.

The blower motor is right by the cabin micro-filter so if you follow the "how to" for cleaning/changing the filter, you will be most of the way there. Here is a link for the filter change: http://www.innerbean.com/housecor/cabin_filter.html
When I was cleaning my microfilter, I was looking around trying to find a leaf/twig that was inside the vent system and rubbing against the fan. I decided it was not worth the time/effort to pull the entire system apart since I only heard the noise on occasion but the motor is right there so you shouldn't have too many more steps to get it out.
Good luck!

It is easy to do. Lie supine in the passenger footwell and crank your head back until your neck almost snaps. Over near the right kick panel, above where a passenger's ankle would be, is the fan. It drops right down.

Look under the dash on the PS. You'll see the bottom of the blower motor. There are like 3 or 4 screws that hold it in. Take them out. The motor drops down. Make sure there isn't any trash or leaves in it. If it's clean turn your AC on and see if the noise is in fact coming from the blower motor and not just trash in the fan. If it's silent check your air vents for trash.
