So I have a very cheap Rogue 5 string bass, and the bridge pickup on it does not work. It is operated by a e way selector that is not attached to a pickguard but rather it is in the cavity in the rear. I've opened it up but don't know how to remove it, fix the problem and reassemble the components.

I'm not taking it to a shop because it's not a very important instrument to me.

So, how should I go about this??
pics please
