Ok, I got my d90 about 3 hrs ago, I'm very excited, however, the fuse to the windshield wipers was blown upon delivery. I changed the fuse, the wipers worked. I then push for the wiper fluid, and then the fuse blew again. What should I do? There has to be a problem somewhere, I just don't know where. If anyone knows a few things to check, please let me know.
