A micro switch can be broken, even if it is clicking, due to oxide on the contact surfaces. Most simple way to make a realistic test, is to connect a voltage meter in parallell over the switch. When not driving the roof, you will read a voltage drop over the switch when the brake pedal is pressed. W...

So you have power on 30 one the fuse board, with removed relay, that is slightly odd. I assume this is meassured with installed fog light bulbs.
