I lead her through testing with a multimeter today. The motor controller gets power, and it outputs power in response to the dash fan controls. The fan motor just does not respond. There was evidence of water intrusion on linings behind the cover panels. Probably some bearings or brushes are rusted and seized.
Now we order the motor and locate and eliminate the leak before installing the replacement.
All the while the kid is learning to use tools, do diagnostics, never force anything, and always test instead of guess if at all possible....
