So I just got some new wiper blades, and the driver side blade doesn't seem to work very well. It seems to skip over the middle and not wipe it. About 1 out of 10 it will do a full pass and be fine. Is there a break in period, do I need to tighten the arm to obtain more pressure? I am just curious as I don't want to drive like this as it is a safety issue. Thanks in advance
