Thor Vegas wiper hits windshield pillar.?

shorter wiper?

Just wondering since it's a 2015 can your dealer solve this for you under warranty?

In addition to the adjustment that Bill described, there is an adjustment on the bolts that hold the motor in place, on mine it is on the left hand wiper. It is difficult to get to.

Check the position of the drive arm at the wiper motor and at the based of the wiper for possible adjustment. The position of the arms with respect to the center pivot point establishes the total swing of the wiper. Closer to the center is less swing.

I suspect the with the OP's coach the offending side either wasn't set correctly during installation or has slipped. Once the swing angle is reestablished you might need to pull the arm as Bill described to reestablish the off or stow position.

If one side is off but the other is good duplicate the position of the good side by measuring the distance from the centers of the pivot and the drive arm. The trick is the amount of room to access the wiper motor and the base of the wiper arms.

I have the same problem on my 05 Itasca. Took it to a garage and the mechanic said he could not fix it. So, I'll be monitoring this post to see if any other ideas surface.

"Usually" where the wiper arm attaches to the arm drive stud, there's a bolt holding the arm to the stud. If so, take out the bolt and pull off the arm. It could be frozen on there and you'll need something like penetrating fluid to help loosen it. Usually the stud is grooved to keep the arm from slipping on it. Take off the arm and move / rotate it a couple of grooves in the direction you think it needs to go. You might get it right the first time or may need to move it a little more. When it's in the right place, replace the bolt.
