The easiest solution is to remove the door card, then unplug the connection to the motor. This has only two wires to it, switchable pos and neg. With a suitable meter, or even a test lamp, you can check if power is reaching the connector - if it is, then power is reaching the motor, and therefore the motor is probably faulty.
I'm not familiar with the GT, but I'm fairly sure that it will be similar to 147 and 156 - the motor and winder assembly will be secured to the door with 4 or 5 10 mm nuts, and will be connected to the window glass with a peg through the glass, secured by a "c"-clip, which pulls off with a modicum of effort. Motor and assembly are normally replaced as a complete unit.
