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

Just ensure that the sunroof drains are clean and clear by passing a thick
and flexible wire down each one at front and up each one at rear
(pre-measure the length which will just clear the upper and/or lower
extremities). Then run some water down the drains at the front to see if
there is any "pooling" at the guttering around the sunroof. It could just be
the wind blowing some water back up the front tubes when it cannot get away
fast enough. Also make sure that the front drains exit vertically downwards
between the fender sections (inner and outer). Problems of this nature can
be very annoying if there seems to be no reason for their happening.

All the best, Peter.
