So I pulled out of my garage the other day and I heard a loud crash...then I realized my tailgate was up! I thought my rear window blew out, but to my surprise it only broke the rear window wiper arm. I bought a replacement at the dealer ($19), but I can't seem to figure out how to get the old arm off. I took the nut off from under the cap but it is really on there! The dealer said to just take the nut off and it slides off. I have tried prying on it but I don't want to damage anything else. Does anyone have any advice? Thanks!
