What determines the timing of the wiper blades. Is it the Onboard Power Supply Control Unit or the colunm switch? After replacing the OPSCU and starting up the car the wipers jumped to 25% above the bottom of the windshield. When I set the column switch to continious the wipers cycle correctly, top to bottom. When there set to intermitten the stop 25% above the bottom of the windshield. When I shut the wioers off the the wipers end at the 25% point. With the column switch off, I can manually move them to tbe bottom of the widshield.
