126 ns window does not work

[pyth0nssec500]

hi
this is the first time im posting on this website and i am in need of some help. I am not a pro but a novice.

I have a c126 and the ns window does not work.

1. i have tested the motor and it works.
2. i know the switch works,

I discounted the conection between the loom and the motor on the door.

with an amp meter i get a reading of 12v on the loom,

with a car batter i tested the motor and it works.

when i conect the motor up it does not work. no power, no 12v coming through.

please help because i am lost.

regards

How old is the car?
I understand that in older models, the motor of the window is driven by a rely. The newer ones are driven through a controller which can go wrong and is time consuming to replace.
