1. A door check mechanism for a vehicle door moveable relative to a vehicle body between a closed position and a fully-open open position, the door check mechanism comprising:

  • a housing connected to the vehicle door and having a linearly moveable actuation member driven by an electric motor; and

    an articulating linkage pivotably interconnecting the actuation member to the vehicle body; and

    a door check device operably associated with the linkage for mechanically holding the vehicle door in at least one intermediate open position in addition to the fully-open position, wherein the door check device is configured to apply a compressive load to the linkage, wherein the compressive load exerted on the linkage holds the door in the at least one intermediate position, wherein the door is held without actuation of the electric motor,wherein linear movement of the actuation member in a first direction causes movement of the vehicle door in an opening direction from the closed position toward the fully-open position and linear movement of the actuation member in a second direction causes movement of the vehicle door in a closing direction toward the closed position;

    wherein the actuation member includes a spindle drive mechanism including a leadscrew supported for rotation in the housing, and a drive nut in threaded engagement with the leadscrew, the drive nut having a pivot post;

    wherein the articulating linkage is connected to the drive nut.
