I'd like to hear other 940 owners tales of noises when it either rains or is windy.

My 1994 945T makes two annoying noises, one when it rains, the other when it' windy.

When it rains:
It seems to me that it's a drainage issue from the vents near the windshield (the ones between the windshield wipers). There is some debris in there, not much though. Anyhow, the sound is like a "fwoomp, fwoomp, fwoomp" and the noise typically happens 3-4 times. Usually, the rain is coming down like cats and dogs...

When it's windy:
It sounds like it's coming from the upper passenger side windshield and sounds like a playing card in a bicycle's spokes. Different pitch though...
Can't see anything obvious around the windshield, am at a loss for where to look next.

Anyone with similar noises?

Thanks,
Zuda
