Abstract: A vehicle HVAC system includes a first air handling module having a blower motor assembly that includes a fan that reverses direction to selectively extract airflow from a vehicle cabin into the first air handling module and communicate a conditioned airflow from the first air handling module into the vehicle cabin.

Abstract: A brazing fixture apparatus is disclosed for holding a heat exchanger core during a brazing operation. The fixture includes a generally rectangular frame including a contact member disposed on one side of the frame and a single lever extending axially along the length of the frame. The lever pivots from a first position to allow placement of the core onto the frame to a second position, in response to gravity, such that in the second position, the lever applies a constant compressive force on the core to hold the core together during the brazing operation.
