WW2.0 middle blower not working

[stampedecarwash]

Hello the middle blower not working do I need a new fan? it seem to be super expensive. is there a part that typically breaks without changing the whole thing?

Hard to say with no information, could be a bad motor, contractor, bearing, or something else.

UPDATE: problem fixed. the wire in the control box was gotten loose out of its contactor.
