my wiper blade cannot seem to stay adjusted. i asked my guy to check it last time and he said it was done. yesterday i was out and it started raining. i turned on the wiper, and again it started to stray to the right - when it came across the windshield it stopped traveling to the right of the driver's line of sight, and went back down to settle on the hood. i got out, and pushed it up the windshield while it was not on, and tried again. this time it went all the way left and right off the left side of the windshield (driver pov). i got out and moved it back, and it strayed right again !! aarrgghh! so, how do i adjust the wiper so that it stays that way and wipes the area in my line of sight !!! side question: at speed the wiper fluid nozzle leaks and spurts onto the windshield. not much, but over time it is annoying. any suggestions?
