Without that, it would probably end up being a lot of probing of connecters and substituting expensive parts and even if you did find the problem, say the BCM is bad, you couldn't fix it anyway without a tech2 to reprogram the replacement and the PCM. Probably towing it to a dealer for diagnosis will be the cheapest route in the end.
Anyway if you haven't yet check all fuses especially ones labeled "IPC", "BCF", "BCF/IGN or IP, check all fuses to see if any are blown. It's probbaly not a fuse but you never know till you check.
Edit: Hey serkski, I didn't see your post till after I posted, yet it looks like we are in agreement pretty much.

I agree, check your fuses first, they would be the simpliest, but they rarley do ever end up being the problem. I would save yourself the headache and take it in. I'd put money on a bad BCM. It is quick and easy to change, just above your left foot when you're sitting in the drivers seat, but it does need to be programmed for your mileagle, car options, motor, these types of things. It's basically something the dealer can only program. I'm not really familiar with the tech 2 tool, maybe if you knew someone that was a mechanic they could program it for you? For a cheaper alternative... Here's a link to one for sale on e-bay. Good luck...

Its a used one, I wonder if you could just throw it in and go?
