I'd need to grab an electrical manual and check, but here is a possiblity; the ignition switch. I believe there is a dedicated line out of the ignition switch to the fusebox, the power runs through the fuse and to the blower motor controller. These ignition switches are notorious for failing like this. The best course to check if this is true is to find the most likely fuse (should be one labelled something like ""blower" or "climate control fan". something like that, and check BOTH sides of the fuse to see if it's getting power at all. You can also try gently turning the key back and forth and see if it suddenly starts working (run it on defrost, that'll give the biggest effect so you'll know immediately if you got power to it suddenly)
