Today is 8/23/21.  Just got off phone with the parts department, the only people that would answer the phone, and they said the technical support line in non existent by phone unless you have a 2012 unit  or newer. They do take emails but unknown when they may get back to you. My question was where is the fuse/ fuse box to my wipers so that I do not crash and can see in the rain.  

They will tell you to make an appointment with THEM for service, or one of their service partners.  They no longer release schematics either.  Since they got my schematic for FREE, I considered hiring an Attorney.
