The windshield washer sprayers for this unit are embedded in the wiper arms. There is a small rubber hose that connects from the base of each of the wiper arms to a small, black, plastic bulkhead pass-through that continues on into the interior of the unit (photos attached). As you can see from one of the photos, one of them has broken and needs to be replaced. Actually, both probably need to be replaced. Any ideas where I could find replacements?
