I have a 2005 4.0, andrecently asI was driving my radio just up and died on me, it kicked back to life for a second, but then was done for good. No lights worked on it, no sign of anything happening when I pressed any buttons. I assumed it must have been a fuse, but then I noticed that the power windows sroped working as well. Both drivers and passanger side. I've checked the fuses and they all seem fine, so before I take it into the shop, I was wondering if anyone had any ideas, or recomedations that I should try first...

thanks
