If the power window motor part number does not match one of the part numbers above, the limit switch must
be reset using the "INSTALLATION WITH RESET SWITCH" procedure.
NOTE:
Some of the power window motors with the part num bers above may appear to have a reset switch, but it will
not reset the limit switch.
INSTALLATION WITHOUT RESET SWITCH - (Motors listed above)
Check the label on the power window motor for the pa rt number. If the power window motor part number does
not match one of the above, use the "INS TALLATION WITH RESET SWITCH" procedure.
NOTE:
Some of the power window motors may appear to have a re set switch, but it will not reset the limit switch.
1. Connect the door harness connector to the power window motor, and rotate the motor more than 5 turns
in the glass raising (up) direction.
2. Install the power window motor onto the regulator.
3. Install the regulator assembly into the door and secure regulator assembly with the nuts and bolt.
4. Install the glass into the door and align with the regulator, then install the glass bolts.
5. Raise the glass to the top position. CAUTION:
Do not operate the glass automatical ly to raise the glass to the top.
6. Reposition the vapor barrier.
7. Install the front door finisher panel. Refer to INT-11, "
Removal and Installation".

• Press the “BACK” switch and the “UP” switch within 10 seconds after turning the ignition switch from OFF to ACC and hold them for
3 seconds or more. Then the buzzer sounds, all indicators of the
preset switch illuminate, and the self-diagnosis mode starts.
• The continuity of each switch and control dials (A/C and AV switch assembly only) at the ON position can be checked by pressing
each switch and turning each control dial. The buzzer sounds and
LED’s will illuminate if the switch is normal.

MAGNET CLUTCH
System DescriptionINFOID:0000000001679808
SYSTEM DESCRIPTION
The A/C auto amp. controls compressor operation based on ambient and intake temperature and a signal
from ECM.
Low Temperature Protection Control
The A/C auto amp. will turn the compressor ON or OFF as determined by a signal detected by the intake sen-
sor and the ambient sensor.
When intake air temperature is higher than the preset value, the compressor turns ON. The compressor turns
OFF when intake air temperature is lower than the pres et value. That preset value is dependent on the ambi-
ent temperature, refer to the following table.
Magnet Clutch Componen t Function CheckINFOID:0000000001679809
INSPECTION FLOW
1.CONFIRM SYMPTOM BY PERFORMING O PERATIONAL CHECK - MAGNET CLUTCH
1. Turn ignition switch ON.
2. Press the A/C switch.
3. Press vent switch ( ).
4. Display shows , A/C. Confirm that the compress or clutch engages (sound or visual inspection). (Dis-
charge air and blower speed will depend on ambient, in-vehicle and set temperatures.)
Can the symptom be duplicated?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK FOR ANY SYMPTOMS
Perform a complete operational check for any symptoms. Refer to HAC-4, "
Operational Check (Front)".
Does another symptom exist?
YES >> Refer to HAC-3, "How to Perform Trouble Diagnosis For Quick And Accurate Repair".
NO >> System OK.
3.CHECK FOR SERVICE BULLETINS
Check for any service bulletins.
>> GO TO 4.
4.PERFORM SELF-DIAGNOSIS
Perform self-diagnosis to check for any codes. Refer to HAC-22, "
A/C Auto Amp. Self-Diagnosis".
Are any self-diagnosis codes present?
YES >> Refer to HAC-23, "A/C System Self-Diagnosis Code Chart".
NO >> GO TO 5.
5.CHECK AMBIENT SENSOR
Check and verify ambient s ensor circuit. Refer to HAC-78, "

SELF-DIAGNOSIS MODE
The following items can be checked during Combination Meter Self-Diagnosis Mode.
• Gauge sweep and present gauge values.
• Illuminates all odometer/trip meters and A/T indicator segments.
• Illuminates all micro controlled lamps/LEDs regardless of switch position.
• Displays estimated present battery voltage.
• Displays seat belt buckle switch LH status.
OPERATION PROCEDURE
NOTE:
• Once entered, combination meter self-diagnosis mode will function with the ignition switch in ON or START.
Combination meter self-diagnosis mode will exit upon turning the ignition switch to OFF or ACC.
• If the diagnosis function is activated with trip A displa yed, the mileage on trip A is reset to 0000.0. (Trip B
operates the same way.)
To initiate combination meter self-diagnosis mode, refer to the following procedure.
1. Turn the ignition switch ON, while pressing the odometer/trip meter switch for 5 - 8 \
seconds. When the diagnosis function is activated, the odometer/trip meter will display tESt.
NOTE:
Check combination meter power supply and ground circuit when self-diagnosis mode of combination meter
does not start. Refer to MWI-30, "
COMBINATION METER : Diagnosis Procedure". Replace combination
meter if normal. Refer to MWI-76, "
Removal and Installation".
