Can also put someone on the inside while spraying with water on outside and see if can see water come thru. I recently found my source of wind noise in my truck by driving and pushing out slightly at the top of w/s and friend did it when became unsafe while driving and hearing air noise pitch change. Sometimes the sealer on w/s breaks down over time like mine did.
