A small chip turn into a crack that runs along the bottom of my whole windshield. Since it is getting replaced I asked about installing the cold weather package windshield on my car. I find the wipers to be nearly useless without it in a good snow. I'm getting really irritated with Tesla service in general lately. Why is this a problem? I talked through how the cold weather package is installed on the car when it is built, which makes it nearly impossible to add on after the fact. I'm okay with that. I just want the damn heater element. I'll hook it up myself. Oh wait, I still can't get service information about the car, no parts diagrams so I have nothing on how to properly dig into things on the car. /rant.
