Abstract: A system for variable engine compartment ventilation in a slim and compact unit with components used in non-related industries. The system can have at least one bank of movable louvers rotatably mounted within a louver frame for guiding a flow of air into a vehicle engine compartment; a motor to rotate the louvers with a motor gear formed on an output shaft rotatably connected in parallel to at least one helix cable by a helix cable drive gear and a louver pinion gear integral with each louver engaging the helix cable along its length; and a control unit for operating the assembly of movable louvers in response to an output signal from a vehicle communication bus. The output signal of the vehicle communication bus can be in response to input from an engine coolant temperature sensor or a vehicle speed sensor.

Abstract: A sunroof assembly with a composite water management assembly having side rails with a water trough connected at one end to end caps and to a pair of corners at the other, which connect to a front rail at substantially right angles to the side rails. This composite assembly can be connected by vibration welding. A reinforcement bar can be connected at substantially right angles to the rearward end of vertically oriented slide tracks snap fitted into substantially the length of the side rails. A pair of mirror slide mechanisms with vertically oriented mounts are retained, but free to slide, within a channel of the slide track and outboard of the water trough. A movable panel such as a glass sunroof are attached to the slide mechanism. A sunshade can be added that also combines water shedding ribs to channel water to the water trough.
