How remove windscreen motor p2 h10 1937

[P27]

We have found the battery leakage !! It's the windscreen motor which has power going to it even when ignition is off!

It doesn't work/operate, but it warm to the touch. Disconnecting the wires solves the battery leakage. But how to remove it for inspection/repair. There doesn't seem to be much info. in the repair, or spares manuals, nor the electrics book.

Does anyone recognise what make/model this is?
Where is it in the electrics diagrams?

And should it have power going to it even with ignition off?
Could it be the gearbox/parking mechanism that's stuck!
