Some more information would be helpful.....
Where are they attached, under the windshield, laying horizontal? Attached at the top of the cap, running vertical? Split windshield?
Are they actually moving as they were designed and going too far, or are they popping up, like they would if you pulled them up to clean the windshield?
I'm just guessing that if you have to remove the TV, the motor and wiper attachment points are in the upper cap.
