Auto Relay

Mounted on relay bracket on cowl in engine compartment (upper center relay). Relay will be energized whenever Engine Thermal Switch or In-Car Thermal Switch is closed and the selector control head is in 'Auto', 'High' or 'DeFog' position and will be immediately energized in the 'De-Ice' position. Closing of the relay supplies current to the blower resistor board in the programmer and allows blower motor to operate in any speed called for by the position of the system controls.
