If you can do this, the performance of the multifunction switch will be visible to you. You will be able to check any leakage of light from the headlight of your vehicle.

If you find the lights are ok according to your command then the switch is ok. But if the lights are not doing their natural duty then the problem is in the switch itself.
You may need to replace it as soon as possible. You also have to check the heat behind the lights. If the lights are becoming overheated then you have to change the switch.
Step 4: Check the MFS Window
After turning the internal lights off and headlights on, you have to check the multifunction window. The main thing you have to check here is any leakage of lights. If the switch is broken then you will find the lights are glowing slightly even after turning them off.
