Blower Motor Relay: Description and Operation
Description
DESCRIPTION
The blower motor relay (1) for the heating-A/C system is a standard size International Standards Organization (ISO) relay. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal function and patterns (2). The blower motor relay is a electromechanical
device that switches battery current from a fuse in the power distribution center (PDC) directly to the blower motor. The blower motor relay is energized
when the relay coil is provided a ground path by the control circuitry within the front control module (FCM).
The blower motor relay is located in the integrated power module (IPM) in the engine compartment.
