HEATER AND MANUAL AIR CONDITIONER (See P.B-174,180.)
OPERATION
DWhen the ignition switch is turned “ON”, the
blower relay is energized. If the blower switch
is turned “ON” (LO, ML, MH, or HI position)
in this condition, the blower is activated through
the circuit via resistor at a speed corresponding
to the blower switch position.TROUBLESHOOTING HINTS
1. Blower motor is energized at one switch position
and not energized at another.
DCheck resistor.
DCheck blower switch.
2. Blower motor is energized only when switch
is positioned in HI.
DCheck resistor.
