Took my 2012 3.8 in to be serviced about a month ago and when I did, they did the TSB on the wiper motors. Only problem is that my wipers now hit the cowl on the down stroke, and don't go all the way up the windshield where they used to. Due to bad experience with the dealer (they are the only Hyundai dealer in the area and they are 50 minutes from my house. Won't be going back there anymore. Yay rural Alabama), how can I go about fixing this myself?
