Rarely, when I turn on the windshield wipers, they will not operate. If I fool around with the arm and restart the car they come back to life.

I am assuming that it is the switch but I was wondering if there were other ideas or things to check.

Does anyone have a process for replacing the wiper switch?

Thanks,
