Power Windows and Locks don't work right

What is your question?

I can only raise and lower the trucks windows from the driver's switches. The other window switches used to work intermittently but now they just don't. (I have made sure it is not because the window lock button is engaged). Recently, I can't get one of the back windows down at all. Also, one of the back locks will only work manually. It started working electrically for a few days once - but then quit again. I have checked fuses as well. How to fix?
