A drive assembly moves a vehicle closure panel from an open to a closed
condition. The drive assembly has a housing and a motor mounted on the
housing. A drum and gear assembly is rotatably mounted on the housing.
The drum and gear assembly has a drum having a helical groove, a gear in
driving engagement with the motor, and a spring biasing the drum in a
winding direction relative to the gear. The drum and gear have a lost
motion connection therebetween. A cable has an end connected to the
closure panel and an opposite end connected to the drum about the helical
groove in the winding direction. The drum rotates in the winding
direction relative to the stationary gear as the closure panel is
manually moved from the open to the closed condition with the spring
maintaining a cable tension. The drum and gear rotate together in the
winding direction upon energizing the motor effecting powered movement of
the closure panel to the closed condition. The motor is afterwards
energized in an opposite direction counter-rotating the gear relative to
the drum back to a start position.
