Any one with this problem? Only when driving, and it is on both passenger and driver windows. Doesn't happen all the time, but when it does, it just drives me nuts. Took it to the dealer one time, and as always, I can't replicate it with the technician next to me!!

 

I've had this too. It comes and goes on the left but was pretty constant on the right. In my car, It was the rear windshield washer hose that runs inside the panel that is behind the seatbelt. I just put some closed cell foam around it and the passenger side tapping is gone. That's what worked for me.

 

Will look into it this weekend!

 

I have this same problem. Been driving me up the wall.
