I recently started to hear a persistent vibration noise coming from the convertible top of my 2014 Boxster. The top was raised and I was on the highway. The noise seemed to go away at speeds below 40mph (65 kph) or if I pushed up on the headliner just ahead of the passenger head restraint (headrest). It felt like I was putting pressure on a cord to keep it from humming or vibrating.
