The wiper on passenger-side stopped working while under heavy rain this weekend. We drove back home (150 km) hoping the drive-side one doesn't break. Surely, this had to be one of the arms in the wiper mechanism since the other wiper was still working. As I'm out of warranty for long now and like to hack around things a bit, I thought I could give it a try and replace the mechanism by myself. I checked if I could find a video about it, but I didn't. (I namely found this funny video where they remove about every panel and trim you can remove on a Model S, but they didn't remove the wiper arms, and this is where I'm stock right now.) Being all by myself, before ordering anything, I wanted to see if I could access the part. I removed the panel you remove to access the fuses inside the frunck, and I was able to take a picture of the culprit (see pictures attached: one showing the arm that broke (I added blue and red arrows showing where it broke) and another of a used wiper mechanism for sale on the web, with an arrow showing where mine broke.) In order to access and replace the mechanism, I have to further remove the panel at the base of the windshield. I'm able to access and remove all the clips, but I have also to remove the wiper arms. I unscrewed them but they won't come off. They are still stock with the screws and the one that is still working still moves with the mechanism. I hesitate to use priers or apply any force. I can't see any locking mechanism. Any suggestions? And do you know about any other issue about removing this panel?
