The module inside the car is just the timer module for the intermittent wipers. It works by sending a battery voltage impulse to the wiper motor in the park position to cause it to activate one sweep then park again. As you lost the wipers parking function, you would also lose the intermittent wipe function. The most common reason for the loss of both would be the board on the wiper motor itself it is the attached image. However I don't like to replace only the board as the motor contacts can fail as well.
