Lo Relay

Located on the evaporator case in the engine compartment. It is energized whenever the selector lever is at "ECONOMY" or "DEF" or whenever the engine thermal switch or the A/C override switch is closed to allow the blower motor to operate at low blower speed. It is possible for the Lo Relay to be energized whenever the ignition switch is in the "ON" position, but the selector lever is at "OFF".
