This toy has few wires inside to operate fan, which blows plastic balls out. These type of toys a popular right now but notorious for not working after a short time. Any info in repairing the fan would be appreciated

If it is definitely the fan, then pulling it apart to the point where you can see the fan will help you see what type and size it is. This way you can order another fan similar to the original and reinstall it and get it working again.
