I have a 96 Nissan Sentra. For the past month or so, I have been having a noise coming from the passenger side wheel well area. It sounds like a piece of plastic is flapping rapidly in the wind. The sound is a rapid "tap, tap, tap" sound. It doesn't have the deeper sound I associate with problems with car components. I have tried tightening down the plastic pieces in the wheel well area to no effect. Also, I recently had my right wheel checked for balance and found no difference. I would appreciate some suggestions on what else I might check.
