Why wont my car start? Was running fine yesterday, my buddy went to roll the window down, but the window regulator is broken, so the window popped out of the frame. While driving home I noticed that all the windows dont work, wipers only work on high speed, various interior lights no longer work, any help out there? What is the problem with this thing? BTW this has happened before, I unplugged the battery and all was well after that. Now that doesn't fix the problem.
