You should be able to scan the BCM to see if turn signal switch is sending signal for turn for right side. The problem sounds like it is not signalling BCM. The Brake and turn signals are separate circuits into the BCM and the BCM turns on the correct lights. Do you have wire diagram of circuit? Let me know if you need it?
