Good day to everyone. I can not seem to make the DC Motor work in this schematic attached here. It was working fine on a breadboard connection, but on its PCB counterpart it failed. Everything is working except for the motor. Pls help i am desperate

On the printed circuit, the nine volt supply is connected directly across the collector and emitter of Q1. If you have powered up the board, there is not much hope for the poor little critter!
The schematic shows pins 1 and 2 shorted together. I assume that is a typo.
