Mode Control Motor
Replacement
1. Disconnect the 7P connector from the mode control
motor. Remove the rod from the arm of the mode
control motor, Remove the self-tapping screws and
the mode control motor.
2.Install in the reveGe order of removal. After installa-
tion, make sure the mode control motor runssmoothlv.
7P CONNECTOR
MODE CONTROL MOTOR
Test
1.Disconnect the 7P connector from the mode control
motor.
Connect battery power to the No. 1 terminal, andground the No. 7 terminal. To avoid damaging the
mode control motor, do not reverse power andgrouno.
MODE CONTROL MOTOR
Using a jumper wire. connect the No. 7 terminalindividually to the No, 2,3, 4,5 and 6 terminals in
that order. Each time the connection is made. the
mode control motor should run smoothly and stop.
lf the mode control motor does not run when jump-
ing the first terminal, jump that terminal again afterjumping the other terminals. The mode control
motor is OK it it runs when jumping the first termi-
nal again.
lf the mode control motor does not run in step 3,remove it, then check the mode control linkage and
doors for smooth movement. lf they move smoothly,
reDlace the mode control motor.

Recirculation Control Motor
Replacement
1. Oisconnect the 4P connector and the wire harness
clio from the recirculation control motor. Remove
the self-tapping screws and the recirculation control
motor,
lnstall in the reverse order of removal. After installa-
tion, make sure the recirculation control motor runs
smoothlv.

4.
Disconnect the 4P connector from the recirculation
control motor.
Connect battery power to the No. 1 terminal, and
ground the No. 2 and No. 4 terminals; the recircula-
tion control motor should run smoothly. To avoid
damaging the recirculation control motor. do not
reverse power and ground.
RECIRCULANON CONTROL MOTOR
Disconnect the No. 2 or No. 4 terminals from ground;
the recirculation control motor should stop at Fresh
or Recirculate. Don't cvcle the recirculation control
motor for a long time.
lf the recirculation control motor does not run in step
2, remove it, then check the recirculation control link-
age and door for smooth movement. lf they move
smoothly, replace the recirculation control motor.

Replacement
1. Disconnect the 5P connector from the air mix con-
trol motor. Remove the self-tapping screws, the air
mix control motor and the flange collar.

Test
1.Disconnect the 5P connector from the air mix con-
trol motor.
Connect battery power to the No. I terminal of the
air mix control moto., and ground the No, 5 termi-
nal; the air mix control moto. should run, and stop
at MAX HOT. lf it doesn't, reverse the connections;
the air mix control motor should run, and stoo at
MAX COOL.
lf the air mix control motor does not run, remove
it, then check the air mix control linkage and
doors for smooth movement.
lf they move smoothly, replace the air mix con-
trol motor.

4.
Measure the resistance between the No. 2 and No. 3
terminals. lt should be approximately 6 kO t 20%.
Measure the resistance between the No. 2 and No, 4
terminals, lt should be approximately 4.8 kO:t 20% at
MAX HOT and approximately '1.2 kO t 20% at lilAx
cooL.

Evaporator Temperature
SensorPower Transistor
Test
Dip the sensor in ice water, and measure the resistance
with a digital multimeter. Then pour hot water on the
sensor, and check lor change in resistance.
Compare the resistance reading between the No. | 8nd
No. 2 terminals of the evaporator temperature sensor
with the specifications shown in the following graph;
resistance should be within the specifications.

Test
1.Disconnect the 3P connector from the oower tran-
st$or.
Carefully release the lock tab on the No. 2 terminal in
the 3P connector, then remove the terminal and insu-
late it from body ground.
Connect a 1.2 - 3.4 W bulb between the No, 1 and
the No,2 cavity on the 3P connectol
Reconnect the 3P connector to the power transistor.
Turn the ignition switch ON (ll). and check that the
blower motor runs.
a lf the blower motor runs at half soeed the oower
transistor is OK, replace the heater control panel.
. lf ths blower motor does not run at half soeed,
reDlaca the Dower transistor.
