I have a 2002 3.2 tl that when I turn the wipers on they start progressing way past their limits off the edge of the windshield. It threw one off its arm one time. At a slow rate of speed it seems to be ok. Anyone have a similar problem that can advise me. Thanks Terry

 

Either you have a bad wiper motor, a broken wiper rod or a loose bolt near where the wiper bolts onto the motor
