Blower Motor Relay Diagram
(C) ConnectorA relay is used to control the power to the fan control for the blower motor. The blower motor relay is turned ON with a signal from the control module. Power voltage is supplied to the blower motor through the fan control.Relay Specifications

When 20 VDC to 30 VDC is applied between terminals (1) and (2), continuity exists between terminals (3) and (5). When no voltage is applied between (1) and (2), continuity does not exist between terminals (3) and (5).
