Blower Motor: Description and Operation
The blower motor is controlled by the heater control panel which receives battery voltage at all times through fuse 47. With the ignition switch in ON
(II), battery voltage is supplied to the control panel through fuse 17. The control panel is grounded at G401.
Battery voltage is applied through fuse 55 to the blower motor relay contacts at all times. With the ignition switch in ON (II), the blower motor relay is
energized and battery voltage is supplied to the blower motor. The power transistor controls the blower motor in all speeds except HIGH. The power
transistor is controlled by the heater control panel. When the heater control panel requests HIGH blower speed, it grounds the blower motor HIGH relay
coil, the relay is energized, which connects the blower motor directly to ground, making the blower run at high speed.
