so I am getting this loud buzzing noise under the passenger side of dash. Sounds like a electrical motor making a harsh buzzing noise that randomly starts and stops. I checked all buttons on climate control and everything under the dash moves quietly like it is supposed to, I think. Also it only seems to randomly do it when I'm at freeway speeds. Will try and record my next trip to see if I can catch it happen. Then I will post the link to the video here. Any ideas before hand will be much appreciated.
