Annoying Sound ?
 

Ok so this is getting really annoying lol. When I drive on the highway is when it mostly happens and seems its when I go over a certain speed the car makes an annoying buzzing sound kinda loud very annoying. At first I thought it was like an overboost sound like my mazda has but now im just confused lol it comes on when it wants to. If anyone can help me id appreciate it. Thanks, Nick

Maybe door or sunroof seal leaking at a certain speed?

Could it be something loose and vibrating behind the dash?

If you haven't solved it, I wonder if it is the ECU cooling fan. Mine (93 GLT) was intermittent for a while, mainly when I shut off the ignition. A tech told me it doesn't harm anything if that fan doesn't work. Just a thought.
