Window motor

Hi all, 

Bit of a problem with my fabia, none of the windows work on my mk2. 

My question is, would a naffed motor on the drivers side cause all windows to fail?

I've had a look at the loom in the door jam, there was a brown wire which had been exposed, but from what I can deduce power is still getting to the motor but it isn't putting back out again, I've tried using a multimeter and am getting a little power. 

I've changed the switch but nothing happens, it'd a bit warm to be stick in a greenhouse
