I didn't figure out which fuse it was as I discovered the battery needed charging and that fixed it. There are some fused of that size in the two fuse boxes under the hood, you may can pull to see if they are blown.
One thing I didn't do that I should have was call the parts department and ask them; some times you get lucky. You may need to call one dealer to luck up on someone that knows. This shouldn't be as hard as it is. I guess you could pull suspect fuses and when it doesn't power it you found it.
Good luck.
