Could be a bad relay in the RCM. Just because they look good doesn't mean they are. I get RCMs from Florida that have corroded relay cores that will cause the relay to sometimes not work. Open the RCM and remove the spring off the back of a relay then remove the armature arm. The core should be just bare metal without corrosion. Could also be a relay coil going bad.
