I think I've got some wiring schematic pdf files if you pm me your email address. They're for an '02 XL-7.
First I'd make sure the belt didn't fly around and disconnect either the harness connection to the compressor or any others you can find in the neighborhood. If that's still intact, make sure the A/C fuse isn't blown (it has, in my '02 anyway, its own little black fuse holder right in front of the battery.) On mine, blowing that fuse didn't have any effect on the blower motor, but who knows.
