• an electric motor having an output shaft,
• a clutch pack including a first clutch driven by the output shaft, a second clutch driven by the first clutch and wherein one of said first clutch and said second clutch is a one way clutch and the other of said first clutch and said second clutch is an electromagnetic clutch;
• a pinion gear driven by the second clutch;
• an output gear driven by the pinion gear;
• a cable drum driven by the output gear and journaled on a fixed shaft journaled in the cable drive housing;
• a cable connected to and driven by the cable drum and connected to a vehicle power liftgate,
• a spring connected to the fixed shaft and to the cable drum;
• and
• a mechanical fastener connected to the cable drive housing and the fixed shaft that holds the fixed shaft in a position in which the spring biases the cable drum in a direction that urges the cable drum to rotate in a direction that winds the cable onto the cable drum, and
