Problems with wipers..... 05 X5

[RONBUTZJR]

I’m new here, so bare with me please. This site has been awesome in teaching me so much so far so here goes guys. I just bought my first X5 2 months ago, it’s 2005 X5 3.0i and I love it!!! When I bought it the driver’s side wiper was making a stuttering noise on the up-stroke and it also leaves a 4-6 inch un cleared section throughout the middle of the windshield on the down stroke. This happens on the driver side blade only, it wipes on the outer edges but not in the center. Is there a way to adjust the wiper and or a way to fix this problem? When I replaced the wiper blades I used a 24” driver, 22” passenger, and 18” rear blades…. Thank you for any help given.
