ABSTRACT:
A control apparatus for a pivotal/sliding roof panel powered by a reversible electric drive motor operative to move a roof panel from a closed position in a roof opening in a vehicle to either of a venting or an open position. The control apparatus includes a first, operable switch which connects electrical power in one of two opposite polarities to the electric drive motor. A sensor detects when the roof panel is in the closed position. A control device, energizable by the activation of the first switch and the output of the sensor when the roof panel reaches the closed position from either of the venting or open positions, switches its output to disconnect the drive motor from the source of electric power. A switchable member, responsive to the sequential de-activation and re-activation of the first switch, momentarily energizes the control device to connect the drive motor to the source of electrical power in order to initially move the roof panel from the closed position to either of the venting or open positions.
