Verify the customer’s complaint.
Are the customer’s concerns verified?
Move the temperature control lever.
Is an excessive effort required to move the control
lever?
Move the blower control switch on 4.
Does the temperature door move too easily?
Remove the temperature control cable from the
controller.
Does the control knob slide freely, without the click
stops?
Check the cable for improper routing, kinks, wiring
interference, or other instrument panel interference.
Is there a problem.
Repair as needed.
Is the repair complete?
1. Remove the cable from temperature door.
2. Circle the door manually.
3. Check for door binding.
Is there any door binding?
Check the door seal for proper installation.
Is the door seal OK?
1. Check a binding door for shaft alignment, a bent
shaft, a bent door, or a warped case.
2. Repair as need.
Is the repair complete?
Repair the door seal, as needed.
Is the repair complete?
Check the control binding.
Does the control bind?
1. Reinstall the cable to the door.
2. Check the clearance for the cable to dash com-
partments.
3. Repair any interface.
Is the repair complete?
1. Remove the cable from the control.
2. Check the control for binding.
Does the control bind?
Replace the control.
Is the repair complete?
Replace the cable.
Is the repair complete?Yes

DEFECTIVES IN FAN MOTOR CIRCUIT
Fan Motor Does Not Run
Blown fuse
Battery voltage is low
Faulty wiring
Faulty groundChecksActionCheck for short and replace fuse.
Check battery voltage.
Check connectors’ connection.
Do not apply grease. This can cause voltage down.
Remove body painting and completely ground,
Tighten ground bolts and make sure body ground
connection.
Fan Motor Runs in ‘4’position Only (‘3’, ‘2’, ‘1’ : Does Not Run)
Motor Runs With Poor Blowing
Blown resister temperature fuse
Air leakage in parts connectionChecksActionReplace resistor.
Check heater, cooling unit and blower for proper
connection.
Clogged or blocked intake grilleChecksActionClogged or blocked intake grille reduces blowing
capacity.
Frosted Evaporator
Faulty thermo ampChecksActionFrosted evaporator reduces cooling capacity.
Off compressor and maximize blowing capacity

Fault : intake (recirculation/fresh air) door inoperative
Remove the glove box.
Check No. 24 fuse (15A) in the box.
YesNo
Check that it operates toward each direction after
connecting the battery to the 6C terminal of intake
actuator and ground 6A & 6B to the body.
Wiring side connector
Intake actuator is normal.
YesRepair and replace the intake actuator. No
Check intake actuator linkage and door for
proper operation and repair if necessary.Disconnect 20-pin connector from the airconditioner
control unit.
Check current between the intake actuator (6A, 6B)
and the airconditioner control unit (6,7).
Is there current?
YesRepair open wire between the intake actuator
and the control unit. No
Replace the good control unit and re-check. If no
fault, replace the control panel.
Measure voltage between 6c terminal positive pole
(+) and body (-).
Measured voltage is 12V.
Turn the ignitin switch OFF and disconnect harness
of the intake actuator.
Disconnect 3-pin connector of the intake mode
actuator and turn the ignition switch to ON position.
SECTION 8B
SUPPLEMENTAL RESTRAINTS SYSTEM
CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless
other-wise noted.
