Today I was driving rapidly in very heavy rain. Every now and again this very troubling sound would come from over my left ear (US car) I figured it was the sound of water draining somewhere, like a sunroof drain? The roof was closed but every now and again that gurgly sound would happen.
When I opened the roof (going 70 MPH not too much rain comes in...) the sound would not happen but I can not rule out the wind noise from the sunroof drowning out the gurgle...
Am I correct? Is this 'normal' or a problem. If it's fixable how to do it?
Thanks
