Got a 66 Impala. I believe it has an aftermarket wiper motor on it. When you turn on the wipers, it works fine. But when you turn them off, the wipers still move up and down an inch or two from their resting position. You have to turn off the car and turn the key to the on position and off position a couple times for the wipers to stop.
Today, I got them to stop moving, but when I went over a speed bump, they started dancing again.
Anything I can do to the current motor to make it stop dancing when they are suppose to be off?
