My wipers will often keep running after the switch is turned off. This happens both when actuating the single wipe function or using the continuously on or time delay function. I can think of several possible causes. Maybe someone else has had the same problem and can save me some time by telling me how they fixed it.
The possible causes that come to mind are:
1) The wiper motor has a method of keeping the motor on long enough to get the wiper blades back in the lowered position, even if you turn them off when they are in some other part of their cycle. If this function is somehow sticking it could make the motor just keep going on and on.
2) Conductive crud in the control switch, telling the control unit to keep the wipers on.
3) Some fault in the control module.
Any ideas? Or anyone else experienced the same fault?
