Quick test of the rain window closing feature and auto wiper function I have added to my 2010 north american Volkswagen Jetta TDI.
Modifications performed to obtain these features include: hi-line CECM, Passat/CC auto dimming mirror, Passat/CC rain sensor, rain sensor windshield, wiring and coding changes.
Don't mind the ugly windshield and exposed wiring in this video as this was the test setup. I wanted to make sure everything worked properly before pulling down my headliner and replacing the windshield.
