Replacing the windshield wiper switch
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up or can be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs.
If the fault is permanent, replace the windshield wiper switch because an internal fault has occurred.
