Here is the location of the blower motor (passengers' side under the dash) so you can check it out. Also, I would check the blower fuse 40 amp which is in the under-hood fuse panel. I have also seen the blower motor speed control module go out as well, which if you remove you might be able to see burnt connections or hot spots. Check out the images (below). Let us know what you find.
