Thank you for that great information!!! I just bought my x5 several months ago & the wipers have not worked properly on intermitant. I realized that I had the rain sensor from reading the posts on this web site. I am not sure what the "screen" is, but I am sure that i need to peel off the cloudy glue & find a way to mount it to the window. That is probably what you are talking about as the screen. I am going to work on it this afternoon & see what happens. I truely appreciate your help!
