It could be the switch in the light that blows the fuse. There are actually three different circuits in the switch. It is possible that the one that turns the interior light on/off is shorted to ground because of the bad switch. That could cause a blown fuse.
I would start by replacing the light/switch, It is a simple fix, you gently pry the lens out like you were changing the bulbs, then you will see the screws that hold it in. Remove those and fish the light down so you can unplug the connector. No with it unplugged, replace the fuse and see if it still blows instantly.
If it does it may be that the bad switch damaged the CCM and it will need to be replaced. Install the replacement light/switch unit. If you need to replace the CCM, it needs to be programmed to match your vehicle.
If the fuse holds and everything works, enjoy your vehicle.
