Recently my wipers began acting up. They operate normally when engaged, but when I turn the switch to the "off" position they end up sticking straight up, basically in the vertical position. This happened randomly one day when I shut them off.

This happens as follows:
1. During normal operation, I turn the wipers to "off".
2. The wipers go to the "off" position but then immediately bounce back towards the very leftmost position of their travel, and then bounce about 3 inches of travel to the right, where they eventually disengage and remain motionless, and stuck straight up obstructing my view and making me look like a total douche-bag

Any suggestions on how to reset the wipers to their normal "off" position?
