Check this first:
Open hood, over on right side of engine bay (passenger side)
way in back by the firewall. Remove the black plastic cover. Under the cover is a computer module box, you'll need to remove the lid from this box. Once that's off, you'll see a module with a small clear plastic cover, and under that cover there are some fuses. Check those fuses. Don't worry about fuses that are missing, if they aren't there they don't belong there.
This module is called the Base Module, BM for short.
