It does have a potentiometer, and it is actually, working correctly. Thats the first place I went. The LH motor changes direction when it should but the RH motor controller isn't even sending power to the drive motor at all. I checked the fuses and they're ok, unfortunately!
Lol

Any idea how I can verify the motor controller? It isn't producing and error codes and I swear that might be a clue to follow.

Thx,
