Back driver's side window will only go up not down and it only works with the driver master switch, it doesn't work with the back switch at all other windows working with main switch.

Does that mean just the back switch is bad or could it be the main switch as well

Thank you for the help

Chances are the rear window switch is bad, the down relay or the main window switch is bad. Here is a guide to help test to see where you are losing power/ground:
