BLOWER FAN AND MOTOR CHECK
When battery voltage is applied between the termina ls, check
to be sure that the motor operates. Also, check that there
is no abnormal noise.
RESISTOR RESISTANCE CHECK
Use an ohmmeter to measure the resistance between t he
terminals as indicated below. Check that the measured value
is at the standard value.
Standard value:
Measurement terminalStandard, value
Between terminals 3-2 (LO)1.83’
Between terminals 3-4 (ML)0.87

COMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of
oil according to the procedures described below, an d then
install the compressor.
(1)Measure the amount (x of oil within the
removed compressor.
(2) Drain (from the new compressor) the amount of o il calcu-
lated according to the following formula, and then install
then new compressor.

Disconnect the brake fluid level sensor connector a nd, remove
the brake fluid reservoir from the compressor
the hose still attached.
NOTE
Place the removed brake fluid reservoir in where
it will not be a hindrance when removing and instal ling the
A/C compressor, and tie it
cord.
COMPRESSOR DRIVE BELT REMOVAL
(1) Loosen bolt “A” for holding the tension pulley.
(2) Loosen bolt
for adjustment.
(3) Remove the compressor drive belt.
COMPRESSOR
When doing this work, be careful not to spill the c ompressor
oil.
