would a defective front control interface module cause the lights on the a/c and heater buttons not work? plus the contrllers not work?

Which controllers? The automatic climate control? And what other?
If it was just the lights, I’d suspect a broken connection. If other related things are affected, then the CIM would be a likely suspect.
