If I understand your post, the lights on the headliner are the ones with the problem... If so, from the Wiring Diagram, and the description of the lights that are flickering, it may be the Function Control Center that has an issue. I do know from replacing the headliner bulbs with LEDs that this is not a straight +12v drive for these lights, but a PWM output used to vary the brightness. You might have a look into the output of this module instead of the FRM.

Hope this helps,
John
