[HUMTECH]

Had a hummer in the shop today with exact problem, wipers kinda vibrated on the wind shield and wouldn't move. Helped them a little and they made one swipe then got stuck and vibrated again. Found the wiper transmission pivot points were binding up and not allowing them to move freely on their own without help getting them off the position they were stuck on. had to order a wiper transmission assembly which comes with new motor. should have it Friday afternoon ill post my results.
