Mine had same problem :
If you can hear a click from the relay when you press the button then it usually the wire from chassis to door.
The relay is under the carpet under the n/s rear seats.
To check the switch, subsitute it with a known working one!
To check the motor, remove door panel trim, unplug and connect to a 12V source.
If above work, then it is a broken wire. If this is the case, several others will usually be on their way out too. It's a fiddly job though as I could get at them from inside the car so had to solder onto short bits!
Deffo a broken wire,its just getting the wire out thats the problem
