I would hook it to the hotwire and double check that it is in BL mode not BR mode. Change the setting to BL-FW then to BL-DL or back and forth to whatever your final setting is and see if it changes on the Dashboard of the Hotwire. If you see it changing then see if you still have the code. If so I bet the RS is faulty and you should send it in.

The chances of two faulty motors is low. I would also double check your sensor wire and make sure your A B C leads aren't touching anywhere.
