Thanks Volvodrivingbiker, much appreciated.
Because it appears you've got to the bottom of this, would you mind answering a couple of queries....
* There's two wires going into the motor - one browny/red and one black. Are you saying that these are both 'live', presumably one to send 12v+ for up, the other 12v- for down etc, while the body of the motor is earth? I was assuming that those two cables are the + and - of 12v with the polarity swapped depending on up or down movement.
* Because my mechanism is locked in the 'up' position, it's difficult to follow the workshop manual's instructions for getting the window winding mechanism out because it suggests putting it in the down position, detaching the window rail, then pushing the window up by hand, then taking the mechanism out. I can't see how I can unbolt the motor and also I read that the whole mechanism is sprung-loaded and it could be hazardous to let the mechanism spring apart. Any suggestions about accessing or removing the motor?
* Once the motor is out, is the resistor obvious?
Thanks a lot for looking at this,
John
