Abstract
Abstract A power-driven cowl for an automotive vehicle including a cowl panel which is shiftable between a closed and an open position. The cowl panel covers a front windshield wiper and in the open position uncovers the windshield wiper to allow normal operation. An electric motor causes the cowl panel to shift between the closed and open positions. A cowl forcing member forces the cowl member to uncover the windshield wiper in, for example, an emergency need. A releasable locking member holds the cowl forcing member locked to permit normal automatic operation of the power driven cowl. If the cowl driving electric motor becomes inoperative and the cowl panel is closed, the locking member can be operated by the driver to cause the cowl forcing member to open the cowl panel to uncover the windshield wiper and enable operation thereof.
