REMOVAL OF REFRIGERANT LINE FROM
EVAPORATOR
Plug the open end of the removed hose and the opening
in the evaporator to prevent entry of dust and foreign

CASE COVER, EVAPORATOR REMOVAL
The evaporator, which has been installed in a factory, has
no case cover. Follow the steps below to remove that
evaporator.
1.
Cut the case along the shown line to remove the cooling
and blower unit.
2.
Remove the air thermo sensor from the evaporator, and
then remove the evaporator towards you, being careful
not to damage its core.
INSPECTION
BLOWER MOTOR CHECK
When battery voltage is applied between the terminals, check
that the motor operates. Also, check that there is no abnormal
noise.
RESISTOR CHECK
Use a circuit tester to measure the resistance between the
terminals as indicated below. Check that the measured value
is at the standard value.

AIR THERMO-SENSOR CHECK
Measure the resistance between the sensor terminals in two
or more different temperature conditions. The resistance
values must conform to the values shown in the graph.
NOTE
The temperatures at checking must be within the range shown
in the characteristic curve.
