Going to check the amp draw in tow mode before the next trip with and without the rear wiper fuse pulled. Pulling the rear wiper is no big deal since I don't use it. Oddly enough, when I put the ignition in accessory
and turned the rear wiper to ON with the fuse in.........no power to the rear wiper but front wipers work.
That recommendation always bothered me. If it truly was the rear windshield wiper alone, that would mean the windshield wiper was pulling multiple amps when not doing anything and that simply is not going to happen.
Let's say the rear windshield wiper was pulling 4 of those 8 amps. That would mean the rear windshield wiper was dissipating about 50 watts of heat. Ever touched a 40-watt light bulb? It's hot. But the rear windshield wiper is not even warm.
I suspect, and it's only a guess, that RVi started pulling fuses until the current draw dropped a lot. My guess is that pulling that fuse is killing part of the Body Control Module (BCM) and there's no telling what is really happening.
Plus, the 2018 was the first model year of the redesign. Why is that recommendation only for 2019 and later?
I dunno so I ditched the RVi TBC entirely and just jumpered it out and my battery has never been run down since.
