Abstract: A C-shaped panel is mounted on the engine compartment side of the engine bulkhead structure and has upper and lower walls projecting forwardly form the bulkhead structure to overhang the engine. A vertically extending front wall is spaced forwardly of the bulkhead by the upper and lower walls to define therewith a transverse air flow communicating passage. Air inlet openings are provided in the top wall to admit air into the passage. The C-shaped panel overlies an opening through the bulkhead to communicate inlet air to the heating, ventilating and air conditioning system. A plurality of removable fasteners removably fasten the panel on the bulkhead to permit removal of the C-shaped panel from overhanging the engine to thereby facilitate and enable engine repair and removal. The windshield wiper motor is mounted on the C-shaped panel within the air flow passage so that removal of the C-shaped panel upon release of the removable fasteners also removes the windshield wiper system for repair and replacement.
