Air Mix Control Motor Test
1. Disconnect the 5P connector from the air mix
control motor.
2. Connect battery powertothe No. l terminal ofthe
air mix control motor, and ground the No. 2
terminal; the air mix control motor should run, and
stop at Max Cool. lf it doesn't, reverse the
connections;the air mix control motor should run,
and stop at Max Hot. lf the air mix control motor
does not run, remove it. then check the air mix
control linkage and door for smooth movement.
. lf the linkage and door move smoothly, replace
the air mix control motor.. lf the linkage ordoorstickor bind, repairthem as
needed.. lf the air mix control motor runs smoothly, go to
step 3.

Measure the resistance between the No. 4 and
No. 5 terminals. lt should be between 2.1 k to
3.9 kQ.
Reconnect the air mix control motor 5P connector,
then turn the ignition switch ON {ll).
Using the Backprobe Set, measure the voltage
between the No. 3 and No. 4 terminals.
Max Cool about 1V
Max Hot about 4 V
lf either the resistance or voltage readings are not
as specified, replace the air mix cotrol motor.

Air Mix Control Motor Replacement
1.Remove the under-dash fuse/relay box (see page
22-491.
Disconnect the 5P connector {A) from the air mix
control motor (B). Remove the self-tapping screws
and the air mix control motor from the heater unit.
Remove the rod (C) from the arm (D) of the air mix
controi motor.
Install the motor in the reverse order of removal.
After installation, make sure the motor runs
smoothly.

Mode Control Motor Test
Disconnect the 10P connector from the mode
control motor.
Connect battery power to the No. 1 terminal of the
mode control motor, and ground the No. 2
terminal; the mode control motor should run
smoothly and stop at Defrost. lf it doesn't, reverse
the connections; the mode control motor should
run smoothly and stop at Vent. When the mode
control motor stops running, disconnect battery
power immediately.

MODE CONTROL MOTOR
3. lfthe mode control motor does not run in step 2,
remove it, then check the mode control linkage and
doors for smooth movement.
. lf the linkage and doors move smoothly. replace
the mode control motor.. lf the linkage ordoorsstick or bind, repairthem
as neeoeo.. lfthe mode control motor runs smoothly, go to
step 4.
Use a digital multimeter with an output of 1 mA or
less at the 20 k Q range. With the mode control
motor running as in step 2, check for continuity
between the No. 4,5,6,7,8, and 9 terminals and
the No. 10 terminal individually. There should be
continuity for a moment at each terminal as the
motor moves past each mode position.
lf there is no continuity for a moment at each
terminal. replace the mode control motor.

1.Remove the ECM (see page 11-4).
Remove the relay mount bracket bolt, and move
the relays out of the way.
Disconnect the 10P connector {A) from the mode
control motor (B). Remove the self-tapping screws
and the mode control motor from the heater unit.
lnstallthe motor in the reverse order of removal.
lvlake sure the pin on the linkage is properly
engaged with the motor. After installation. make
sure the motor runs smoothly.

Recirculation Control Motor Test
1. Disconnect the 5P connector from the recirculation
control motor.
Incorrectly applying power and ground to
the recirculation control motor will damge it.
Follow the instructions carefullv.
2. Connect batterv oower to the No. 5 terminal ofthe
recirculation control motor, and ground the No. 1
and No. 2 terminals; the recirculation control motor
should run smoothly. To avoid damaging the
recirculation control motor, do not reverse power
and ground. Disconnect the No. 1 or No. 2
terminals from ground; the recirculation control
motor should stop at Fresh or Recirculate. Don't
cycle the recirculation control motor {or a long time.
RECIRCULATION CONTROL MOTOR
lf the recirculation control motor does not run in
step 2, remove it, then check the recirculation
control linkage and doors for smooth movement.
. lfthe linkage and doors move smoothly, replace
the recirculation control motor.. lf the linkageordoorsstickor bind, repairthem
as neeoeo.

Recirculation Control MotorI
Replacement
1.Remove the ECM (see page 11-4).
Remove the relay mount bracket bolt. and move
the relays out of the way,
Disconnect the 5P connector (A) from the
recirculation control motor (B), Remove the self-
tapping screws and the recirculation control motor
from the blower unit.
Installthe motor in the reverse order of removal.
Make sure the pin on the motor is properly
engaged with the linkage. After installation. make
sure the motor runs smoothly.

Blower Unit Components Replacement
Nole these items when overhauling the blower unit;
' The recirculation control motor (A), the power transistor (B), the blower motor (C), and the dust and pollen filtefs (D)
can be replaced without removing the blower unit.. Before reassembly, make surethatthe recirculation control linkage and doors move smoothly.. After reassembly, make surethe recirculation control motorruns smoothly (see page 2j-36).
