The front right door handle will not unlock when touched. All other handles work. I removed the door panel and inspected the connections and all appear to be ok. I also reprogrammed how the doors respond to a door handle touch to no avail. The black button on the door handle does lock the problematic door. The door will lock from and unlock from all other methods.... lock switch, key fob. I’m looking for troubleshooting advice to how best to determine what is wrong.

thanks
