Blower Motor Relay: Description and Operation
Rear
BLOWER MOTOR RELAY
The blower motor relay for the optional rear heater-A/C unit is a International Standards Organization (ISO)-type relay. The relay is energized when the
relay coil is provided a ground signal by the blower switch. This arrangement reduces the amount of battery current that must flow through the blower
switch.
The blower motor relay control circuit is protected by a fuse located in the junction block. When the relay is de-energized, the blower motor ground path
through the high blower relay is interrupted.
The rear blower motor relay is located in a connector that is secured to the back of the rear heater-A/C unit housing in the passenger compartment.
The blower motor relay cannot be repaired and, if faulty or damaged, it must be replaced.
