I am having a very annoying problem with my Park Ave. There is a noise coming from the vents and it sounds like a peice of paper or plastic is fluttering around from the air coming from the blower motor. It happens all the time except when the controller is set to "mid" position and the air blows thru the mid-level dash vents. If set to blow to floor or any other setting the noise continues. Also, the noise gets more pronounced as the fan setting is increased. Any ideas on what this is? Thanks

Pretty much answered your own question, either something fell down one of the vents or a blower fan problem.

Had the same problem.Pulled the fan and there was some paper in the fan.Looked like it came from some insulation or something thats near the fan.
Took the paper out,picked out what other pieces i could see and QUIET again.:redface:
