When Blower Switch is in · (Low), • (Medium) or
(High) Position
When the main switch (2) and blower switch (6) is
turned ON, the current flows from battery (1) to A/C main
relay's coil and A/C main relay (4) is turned ON. As the
A/C main relay (4) is turned ON, the current from battery
(1) flows to the blower switch (6) through the blower
motor (5) as follows.
(a) Type 1 (Swash Plate Type Compressor)
"·" (Low) Position
Battery (1) → Slow Blow Fuse → Fuse → A/C Main
Relay (4) → Blower Motor (5) → Blower Resistor (7) →
Blower Switch (6) → Ground.
"•" (Medium) Position
Battery (1) → Slow Blow Fuse → Fuse → A/C Main
Relay (4) → Blower Motor (5) → Blower Resistor (7) →
