Is it possible I got the wrong windshield on my MS? Took delivery of a EAP HW2 with Sub Zero package Model S two weeks ago. This weekend I noticed that the windshield does not have the wipers defrost lines, similar to what shows up here: Did Tesla removed that from the Sub Zero package? Or I got the wrong windshield? In the Control settings-> Cold Weather tab, I do have the option to turn the wipers defrost ON but what does it really do without the defrost lines in the windshield? Can someone with HW2 and Sub Zero package confirm that they got the wipers defrost lines in their windshield?
