1. A window regulator, comprising:
a first guide rail;
a first cursor slidably mounted to the first guide rail;
a second guide rail spaced from the first guide rail;
a second cursor slidably mounted to the second guide rail;
a housing that is not mounted to either the first guide rail or the second guide rail such that the housing is free floating with respect to the first guide rail and the second guide rail;
a motor mounted to the housing and operably coupled to the first cursor and the second cursor such that operation of the motor will cause the first cursor to slide along the first guide rail and second cursor to slide along the second guide rail;
a cable drum rotationally mounted to the housing, the cable drum being operably coupled to the motor;
a first cable secured to the cable drum at one end and the first cursor at another end;
a second cable secured to the cable drum at one end and the second cursor at another end;
a third cable secured to the first cursor at one end and the second cursor at another end;
a first cable sheath surrounding the first cable that extends from a first feature of the first guide rail to the housing;
a cable tensioner associated with the first cable sheath;
a second cable sheath surrounding the second cable that extends from the housing to a second feature of the second guide rail; and
a third cable sheath surrounding the third cable that extends from the a second feature of the first guide rail to a first feature of the second guide rail, wherein the window regulator is configured for raising and lowering a window of a frameless door assembly of a vehicle, wherein the first guide rail has a rectangular periphery and a portion of the first cursor completely surrounds the first guide rail and the second guide rail has a rectangular periphery and a portion of the second cursor completely surrounds the second guide rail.
