Interior Light comes on while driving

Hi,
I have an '04 F-150 4.6L Supercrew 2WD. Recently the interior light will randomly come on while I am driving. Early this week I was having an issue with a parasitic drain on my battery. I traced it down to Fuse location 21 and from there Dr. Google suggested either the Body Control Module or the Dimmer switch could be the culprit. It made sense to me to try the dimmer switch module first as this would explain the interior light turning on randomly while driving. Pulled the module, dusted it off, plugged it back in and parasitic drain is gone. But that dam light is still turning itself on randomly while driving. Eventually it does turn itself off. Wondering if I should just replace the module or could it be something else.

Thanks in advance
