2001 H1 which I started for first time since 2010....my wipers run fine except when off they stop smack vertically in the middle of windshield instead of on upper corner

Any idea?

ANY H1 mechanic around Western PA? I have service manual but it;s been 10 years since I last work on it and I am rusty,

 

Maybe the blades are installed in wrong position? Remove blades and note start and stop points?
