Pico-4WD-car Wheel not turning

Hi, on my pico-4wd the rear-right wheel isn’t working probably, or at all.
Running the test_motor.py from the github repo only spins the other three wheels…
Switching around the Motor between the connectors shows the Motor itself is fine .. rear right is turning on Motor 3 Port for example.
I measured GP10 and GP11 from the PicoPi and they both seem to output 1V. I believe only one should output Voltage depending on the direction, right?
I only have a multimeter to probe around so I’m not quite sure my assessment of the problem is correct so maybe someone has another idea :slight_smile: and can help me fix it.

Thanks for the help.
kind regards
