ABSTRACT:
A heating and air-conditioning (HVAC) module for an automotive vehicle wherein the electric motor for the blower includes a double walled motor housing for noise abatement. The housing defines a cup-shaped inner casing with an open end and a closed end. An outer casing surrounds and is integrally connected to the inner casing by an integral flange. The outer casing extends upwardly from the flange to a rim to define a space surrounding the inner casing. An end cap includes a groove to engage the rim and extends over and in spaced relationship to the closed end of the inner casing. The end cap is held in place by fasteners threadedly engaging posts extending upwardly from the flange, with one of the posts extending upwardly from a female electrical connector that extends radially between the outer casing and the inner casing for supplying electrical power to the motor.
