really? 8 years being a mechanic i have never seen any make or model have a set up like that, cause normally you just take the wiper arms off, make sure the wiper transmission is in the down position then re-instal
after googling it, yeah i see that little nub on where the arm attaches. that is very strange. i wonder if it was to combat the previous year gm's where the wiper arm used to strip off the gear
