Intermittent Wipers
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
When the wiper switch is in the intermittent setting, the wiper motor activates at timed intervals. The lower the setting, the longer the interval between wipes.
If equipped with rain sensitive wipers, the rain sensitive wiper feature must be disabled for the standard intermittent wiper function to operate.
