Blower Motor Relay: Description and Operation
BLOWER MOTOR RELAY
The blower motor relay is a International Standards Organization (ISO)-type relay. The relay is a electromechanical device that switches battery current
to the blower motor.
When the blower motor switch is in any position except off, and the ignition is turned on, the blower motor relay is energized and provides battery feed
to the blower motor from a fuse in the fuse block module through the blower motor resistor.
The blower motor relay coil is controlled by a voltage signal from the blower motor switch.
The blower motor relay is installed in a wire harness connector located near the passenger side outboard end of the Heater-A/C housing in the passenger
compartment, next to the Heater-A/C wire harness connector.
The blower motor relay cannot be repaired and, if faulty or damaged, it must be replaced.
