So the direction relay is not clicking into reverse. I'd measure coil resistance across the 2 big pads on left. Per datasheet for the 845N-2C-S 5V, it's about 50 ohms.
If that checks out, by inspection you can see the 5630 SOT-23 N-FET driving the relay. Does this pin get pulled down (one side of relay coil tied to +5V as indicated) when commanded into reverse? If not, then maybe the N-FET is toast (FDN5630). Of course the N-FET gate pin as indicated is high when the relay is driven. If this pin does not go high then that's a digital signal from the processor electronics at which point all I can say is good-luck!
