I have the vehicle listed above Polo 9n and the passenger side window works for a small amount of time and then completely stops no clicking/sound from motor when button is pressed. The only way I can get it to work again is to remove the door card and unplug the motor for 30 seconds and then it works again for a short period. I have checked the wiring in the door and in between all seems fine. I have also changed the motor and switch but having no success in a normal working window. Please help

It sounds like the master window switch is bad. To be sure this guide can help you test the power and ground to see where you are losing power:

I have found that both motors have a constant 12v power to each. However, when I unplug and plug the passengers motor back in for it to start working my test light will no longer light up while touching the constant power supply wire in the driver's motor? I am so confused with this now.
