I was driving my Z today on the highway and noticed a vibrating noise from the passenger side door. The thing is, it only happens at around 70mph and over. anything less than 70mph, no noise. Anyone experience this???

 

I have the same thing, but I thought it was from under the passenger seat.

 

Is your passenger seat belt in the clip to keep it from rattling?

 

i have just noticed the same thing. Seems to only happen at 65 mph, and up. i am wondering if mine is from the passenger door. and yeah, i have the seat belt clipped, so not sure what it is.
