HEATER BLOWER MOTOR OPERATION
CURRENT IS APPLIED AT ALL TIMES THROUGH THE HTR FUSE TO TERMINAL 5 OF THE HEATER RELAY.
WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 1 OF THE HEATER RELAY

*LOW SPEED OPERATION
WHEN THE BLOWER SW IS MOVED TO LO POSITION, THE CURRENT FLOWS TO TERMINAL 5 OF THE BLOWER SW "TERMINAL 6

THE BLOWER RESISTOR "TERMINAL 4 "GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT LOW SPEED.

THE BLOWER RESISTOR "TERMINAL 2 "TERMINAL 1 OF THE BLOWER SW "TERMINAL 6 "GROUND. THIS TIME, THE
BLOWER RESISTANCE OF THE BLOWER RESISTOR IS LESS THAN AT LOW SPEED, SO THE BLOWER MOTOR ROTATES AT
MEDIUM LOW SPEED.

THE BLOWER RESISTOR "TERMINAL 3 "TERMINAL 2 OF THE BLOWER SW "TERMINAL 6 "GROUND. THIS TIME,
RESISTANCE OF THE BLOWER RESISTOR IS LESS THAN AT M1 POSITION, SO THE BLOWER MOTOR ROTATES AT MEDIUM HIGH
