discovery passenger window wont work

hi there im a bit stuck so any info will help, my passenger window has stoped working, iv tried switches that work other windows and even tried a different lift ecu, the motor works because iv tested it with a live and earth to the battery. im just a bit stuck so any fresh ideas and il have another go in the morning, cheers

loom threw door broken wires

Front or rear is the question

front 3 door

As with yours mine did nothing, so I swapped with one of the other switches and the motor made a noise but still nothing happened, I took the door card off and found that a plastic wheel in the runner of the window regulator had disintegrated.

I changed the window regulator and put in a new switch and all working again
