Hey,
I had a knock also going on on the right side of the winshield, it was during the summer when it got really hot.
I spent about a month to two months trying to figure it out and i ran some experiments,
In my case it has something to do with the cowel, the black plastic piece that runs along the botton of the windshield.
When I'd hear the noise on my way home I'd get home and take the cowel off, a bit of work, take wipers off, disconect washer fluid line but nothing hard, and no noise, when I put it back the noise would appear.
The reason I didn't take it to the dealer was because it was so on and off.
I went a week with no cowel on my windshield, hence no wiper blades, I had to hope it didn't rain but i work close to home...anyways that whole week I never heard it once...I did the test for a week twice.
When i put it back the noise came back a day later.
I did the cowel on and off thing about a dozen times over the course of two months, every time I had the cowel off I never heard the noise.
So, it has something to do with that 100%, just weird that it only occurred when it was hot out.
Still can't figure out what is going on, what is contacting the cowel ???
Its winter now so I don't hear it.
