A mounting method and apparatus provides a simple and compact mount for attaching a power or manual window drive mechanism within a door module. The drive mechanism can be removed from a door panel without having to remove the driven mechanism that lowers and raises the window. The drive mechanism is positioned on one side of the panel and the driven mechanism is positioned on an opposite side of the panel from the drive mechanism. A retaining assembly retains the driven and drive mechanisms to the panel such that the drive mechanism can be selectively detached from the panel without detaching the driven mechanism from the panel.
